Dogs, much like human beings, can develop allergies and sensitivities to various foods. These adverse reactions can manifest in a multitude of ways, from pesky skin irritations and relentless itching to more serious gastrointestinal issues like vomiting and diarrhea. These symptoms can significantly affect a dog’s quality of life and turn mealtime into a source of discomfort rather than joy.
By being vigilant and proactive, introducing new foods gradually, and working closely with a vet, we can make sure our dogs enjoy their meals without the drama of allergic reactions or food sensitivities. Armed with the right knowledge and approach, we can keep our furry friends feeling their best and feed them a diet that supports a long, healthy, and happy life.
Here you’ll find a wealth of information on how dogs come to have allergies and sensitivities to food, what we can do to prevent and manage them, what some of the most common dog food allergies and sensitivities are, and which breeds are the most commonly affected.

How Dogs Develop Allergies and Sensitivities
Food allergies in dogs occur when their immune system gets its wires crossed and mistakenly identifies a harmless food protein as a dangerous invader. Our dogs’ immune systems overreact by sounding an alarm and mounting a full-on attack against something as simple and harmless as a piece of chicken. This overreaction then leads to a range of undesirable symptoms, from relentless itching, licking, and inflammation to uncomfortable digestive issues like vomiting and diarrhea.
In contrast to food allergies, food sensitivities and intolerances don’t trigger the immune system to go on the offensive. Instead, the effect is that our dogs’ digestive systems struggle to break down certain ingredients. It’s a digestion hiccup rather than an allergy immune response. Common culprits here include lactose in dairy and gluten in wheat, which cause a dog to experience gastrointestinal discomfort without triggering an immune reaction.
Understanding the difference between food allergies and food sensitivities, identifying the symptoms, and taking appropriate action are key to managing a dog’s diet and keeping them healthy and happy. It’s all about knowing what to avoid and how to feed our furry friends the nutrients they need without the drama of an allergic reaction.
Preventing and Managing Dog Food Allergies and Sensitivities
Preventing every food allergy or sensitivity in dogs isn’t always possible, since genetics and environmental factors play a significant role. However, that doesn’t mean we’re powerless. By taking some proactive steps, we can minimize the chances of our pets developing issues in the first place and learn to manage them effectively if and when they do arise.
First and foremost, introducing new foods gradually is key. Doing so gives our dogs’ digestive systems a chance to adapt and allows us the time we need to monitor their behavior for any adverse reactions. This slow introduction is crucial to spotting potential allergens early on.
Another effective strategy for managing allergies in dogs is an elimination diet, which should be supervised by a veterinarian. This process involves removing all suspected allergens from a dog’s diet and then slowly reintroducing ingredients one at a time in an effort to identify the specific culprit. Once the allergenic ingredient is found, the best way to prevent symptoms from flaring up is to avoid it altogether.
Feeding a dog a balanced diet with high-quality, hypoallergenic ingredients plays a significant role in reducing the overall risk of developing allergies or sensitivities. Hypoallergenic dog foods are formulated to minimize all potential allergens and use novel proteins (protein sources that are less common in dog food) and limited ingredients, making them a safe choice for sensitive dogs in the majority of cases.
By being vigilant and proactive in our approach, we can rest assured that our canines are healthy and enjoy their meals without discomfort. Regular vet check-ups, monitoring dietary changes, and feeding our pups the right foods are all part of maintaining a dog’s inner peace.
10 Common Dog Food Allergies
Recognizing the common culprits and understanding the various symptoms that accompany dog food allergies and sensitivities is an important step in managing a dog’s diet and ensuring their health. Here are ten food allergens that most often affect dogs, along with detailed insights into each one.
Beef
Beef is the most common food that dogs can be allergic to, and this allergen affects a significant number of pets worldwide. When a dog is allergic to beef, their immune system mistakenly identifies the proteins found in the meat as harmful invaders, which then leads to a range of uncomfortable symptoms including intense itching, skin inflammation, and gastrointestinal issues like vomiting and diarrhea. In some cases, the symptoms can escalate into more severe reactions, ultimately causing distress for both dog and owner.
Given its widespread use in commercial dog foods, beef is often the first suspect when food allergy symptoms reveal themselves, prompting pet owners to switch to alternative protein sources for their dogs. Recognizing these allergic reactions will help owners make informed decisions about their pets’ diets, ensuring healthier and happier lives for their furry companions.
Chicken
Another frequent offender is chicken. Chicken can cause allergic reactions that are very similar to those seen with beef allergies. Symptoms commonly include skin issues such as redness and itching, which lead to discomfort and irritation for the affected dog. Digestive problems like vomiting and diarrhea may be present as well, varying in severity. In some cases, these reactions also manifest as chronic ear infections or respiratory problems, making the general health of the dog a significant concern.
Chicken allergies hold their place as one of the most common food allergies in dogs because chicken is just as popular an ingredient in dog foods as beef is. Pet owners need to be highly vigilant in monitoring their dogs for any signs of allergies and adjust their diets appropriately, especially when dogs show a sensitivity to poultry. It’s a good idea to consult with a veterinarian and explore alternative protein sources to ensure a dog’s being fed a well-balanced diet that avoids triggering bad reactions.
Dairy
Dogs with dairy allergies generally have difficulty digesting lactose, leading to gastrointestinal symptoms like gas, bloating, and diarrhea. These digestive issues are quite uncomfortable for pets, often resulting in behavioral changes like decreased appetite or lethargy. on top of these gastrointestinal problems, some dogs may also develop skin issues, including itching or rashes, which further exacerbates their discomfort.
Dairy products like milk, cheese, and yogurt are common triggers of these allergic reactions, and pet owners need to faithfully read ingredient labels to avoid any foods that contain hidden dairy. When introduced into a dog’s diet, even very small amounts of dairy can lead to an allergic reaction, so it’s essential for owners of these sensitive dogs to find suitable treats and meals that don’t contain lactose.
Fish
Although less common, some dogs are allergic to fish, a protein source that’s often considered hypoallergenic. Symptoms typically include skin irritations, which may manifest as itching, redness, or inflamed patches, and gastrointestinal problems such as vomiting and diarrhea, which then lead to further complications like dehydration if not addressed promptly.
Fish allergies can be tough to manage, especially if a dog was put on a fish-based diet for other health reasons. Finding alternative protein sources that meet their dietary needs often requires a bit of detective work and consultation with a veterinarian. It’s essential for all dog owners to monitor their pets closely and seek professional advice immediately when they suspect a fish allergy. Early intervention will help alleviate discomfort and prevent more serious health issues down the line.
Wheat
Wheat allergies often lead to a variety of symptoms, including itching, ear infections, and gastrointestinal issues, any of which significantly impact a dog’s quality of life. Dogs with wheat allergies may also experience chronic skin conditions, like dermatitis or rashes, which can be particularly uncomfortable and might need ongoing treatments.
Because wheat is such a common ingredient in many commercial dog foods and treats, owners must always read labels and choose appropriate alternatives in order to avoid the wheat allergen. This could involve selecting grain-free options that are specifically designed for dogs with food sensitivities. Additionally, consulting a veterinarian early on can help to establish a suitable diet and manage the allergy effectively, ensuring that our furry companions are healthy and happy despite their dietary restrictions.
Lamb
Though less common, some dogs will develop allergies to lamb, which may surprise some pet owners who believe it to be a safe protein source. Symptoms are similar to those of other food allergies: skin issues, such as itching and rashes, as well as digestive problems, which commonly manifest as vomiting or diarrhea.
Lamb is used as a novel protein in many hypoallergenic dog foods, specifically formulated for dogs with sensitivities to common proteins like chicken or beef; however, it’s important to recognize that some dogs can still be allergic to it. Identifying a lamb allergy often requires a diagnostic process, which frequently include elimination diets and veterinary consultations, to make sure a dog is getting proper nutrition without triggering any allergic reactions.
Soy
Soy allergies also cause skin issues including itching and redness, as well as gastrointestinal problems like vomiting and diarrhea. In some cases, dogs with food allergies may also exhibit symptoms of anxiety or lethargy due to their discomfort.
Soy is a common ingredient in a lot of dog foods, often used as a source of protein or as a filler, and it can be difficult to avoid. This makes it a challenging allergen for dogs and their owners. As a pet owner, it’s imperative that ingredient labels are read carefully, and alternative protein sources are used to ensure we’re making the healthiest choices. Consulting with a veterinarian will provide any necessary insight for managing a soy allergy and finding suitable dietary options that keep our dogs happy and healthy.
Corn
Corn is another potential allergen that can cause itching and gastrointestinal issues in dogs. When exposed to corn, dogs with corn allergies commonly experience chronic ear infections and skin problems, which inevitably lead to discomfort and a decreased quality of life. It’s not uncommon for corn allergies to manifest themselves through frequent scratching, hot spots, or even digestive disturbances like diarrhea or vomiting.
Since corn is another common filler in many commercial dog foods, it’s a widespread allergen that can affect a significant number of pets. Due to its prevalence in the pet food industry, owners must stay vigilant about reading ingredient labels and swapping in alternative diets that prioritize other natural ingredients. Early awareness of this issue will help prevent unnecessary health complications and offer some solace that our canine companions will thrive on a diet that suits their individual needs.
Egg
Dogs with egg allergies often suffer from skin issues and digestive problems, resulting in a significant impact on their overall quality of life. Eggs are another common ingredient in many dog foods and treats, again making it challenging for pet owners to identify, especially since they’re often advertised as protein-rich and nutritious options.
Symptoms frequently include itching, redness, and gastrointestinal discomfort, which may manifest as vomiting or diarrhea. These reactions can also lead to chronic skin conditions if left untreated, requiring the attention of a veterinarian to develop a new, suitable dietary plan. Managing allergies in dogs with an egg allergy involves reading ingredient labels carefully and finding alternative protein sources to keep their pets healthy and happy by avoiding this allergen.
Pork
While rare, some dogs develop an allergy to pork. Symptoms are the same as other food allergies and include itching, skin inflammation, and gastrointestinal issues like vomiting and diarrhea. These reactions vary in severity and typically manifest shortly after the consumption of pork or pork-based products.
Pork is less commonly used in dog foods, so pork allergies are reported less than others, but it can still be a trigger for some dogs, particularly pups with a history of food sensitivities or allergies. Dog owners need to stay vigilant and consult a vet if they notice any adverse reactions after their pet eats pork. Prompt attention helps to manage these dog food allergies more effectively and positively contributes to a pet’s holistic wellness.
Common Dog Food Sensitivities
Food sensitivities in dogs are a bit different from allergies. Unlike allergies, which involve the immune system going haywire over a specific protein, food sensitivities are usually digestive issues. This means a dog’s tummy just can’t handle certain ingredients, leading to symptoms that make everyone involved pretty uncomfortable. Recognizing these sensitivities and learning how to manage them will help us keep our pups happy and healthy. Here are some common food sensitivities seen in dogs, along with detailed insights into each one.
Dairy
Dairy is a frequent offender when it comes to food sensitivities in dogs. If a dog is sensitive to dairy, they have difficulty digesting lactose, the sugar found in milk and other dairy products. This often leads to gastrointestinal issues such as gas, bloating, and diarrhea. Lactose intolerance is quite common, and the symptoms can vary from mild discomfort to more severe digestive upset. If a dog shows these symptoms after consuming dairy, it’s best to eliminate these products from their diet entirely.
Wheat
Some dogs have trouble digesting wheat, which also leads to a variety of gastrointestinal issues. Wheat sensitivity manifests as bloating, gas, and diarrhea, just like dairy does. If a dog is sensitive to wheat, the problem lies in their digestive system’s inability to properly break down the proteins found in it. Switching to a wheat-free diet is the first step to alleviate these symptoms.
Corn
Corn is another common ingredient that some dogs struggle to digest. Sensitivities to corn typically result in gastrointestinal problems akin to those caused by wheat and dairy: gas, bloating, and diarrhea. Since corn is often used as a filler in many commercial dog foods, it can make for a widespread issue. If it’s suspected that a dog has a corn sensitivity, start by looking for dog foods that use different carbohydrates like sweet potatoes or peas.
Breeds With Higher Risk of Food Allergies
While any dog has the potential to develop food allergies, some breeds are more prone to these problems due to their genetic makeup and physical characteristics. Knowing which breeds are most susceptible to dog food allergies should motivate owners to take proactive steps to mentally prepare, manage and prevent them.
Some of the most commonly affected breeds and why these dogs are more likely to suffer from food allergies and sensitivities than others are listed here:
Labrador Retrievers
Labrador Retrievers, with their boundless energy and love for food, are unfortunately prone to allergies. These lovable furballs often have high levels of immunoglobulin E (IgE), a protein that triggers allergic reactions. Having this protein in abundance sometimes leads to environmental allergies, like to pollen and dust, as well as dog food allergies to common ingredients like beef, chicken, and dairy. Given their adventurous nature and their tendency to sniff out every crumb, Labrador Retrievers are often exposed to a variety of potential allergens.
Golden Retrievers
Golden Retrievers are the epitome of friendliness, but their sensitive skin makes them vulnerable to allergies. They often develop atopic dermatitis, an allergic skin condition, due to their genetic predisposition. Environmental allergens like grass, pollen, and dust are frequently the culprits, along with dog food allergens like chicken and beef. Their social butterfly lifestyle means they’re constantly in environments where allergens lurk.
German Shepherds
Noble and protective German Shepherds are also predisposed to allergies. Their sensitive immune systems will overreact to certain proteins, leading to dog food allergies, especially to beef, chicken, and dairy. Their active lifestyle and frequent outdoor activities expose them to a wide range of environmental allergens.
Cocker Spaniels
Cocker Spaniels, known for their silky ears and gentle demeanor, have particularly sensitive skin. They’re prone to atopic dermatitis and environmental allergies. Their love for exploring grassy fields often exposes them to allergens like pollen and dust. Their long, dense coats have a tendency to trap allergens, making their symptoms more pronounced. Dog food allergies are also common with Cocker Spaniels, with beef, dairy, and wheat being the usual suspects.
West Highland White Terriers
West Highland White Terriers, or “Westies,” are small but their chances of developing allergies are not. These little dogs have a genetic predisposition to atopic dermatitis and environmental allergies. Their dense coats often trap pollen and other allergens, leading to itching and skin irritations. Dog food allergies to proteins like beef and chicken are also common in this breed.
Poodles
Poodles, especially the Standard variety, are known for their intelligence and their hypoallergenic coats. However, they can still suffer from atopic dermatitis and environmental allergies due to their sensitive skin. Their curly coats, while stylish, can trap allergens and exacerbate their symptoms. They’re also susceptible to common dog food allergies, frequently reacting to ingredients like beef, dairy, and wheat.
Chinese Shar-Pei
Chinese Shar-Peis have a unique look with their wrinkled skin and stoic expressions, but these features also make them prone to allergies, unfortunately. They often suffer from atopic dermatitis and environmental allergies. Their wrinkles will trap allergens, which then leads to skin irritations and infections. Dog food allergies, particularly to beef and chicken, are also a common concern for this breed.
Dachshunds
Dachshunds, with their long bodies and adventurous spirits, aren’t immune to allergies. They’re another breed that’s prone to atopic dermatitis and environmental allergies due to their sensitive skin. Their long ears trap allergens, resulting in ear infections and itchiness. Dog food allergies, especially to beef, dairy, and wheat, are also common.
Safe(r) Food Choices
When it comes to managing a dog’s diet, especially for those with dog food allergies and sensitivities, it’s essential to feed them ingredients that are less likely to trigger allergic reactions. While it’s difficult to say that any food is completely free from the risk of causing or triggering an allergy or sensitivity in all dogs, there are some “safer” foods that are generally considered to be less likely to cause reactions. These include:
- Hydrolyzed Protein is a type of protein that’s been broken down into super small pieces so that it’s less likely to cause allergic reactions in dogs. Think of it as pre-digested protein, making it easier on their tummies and less likely to set off their immune systems. This type of protein is great for pups with food sensitivities because it reduces the chances of them reacting negatively while still providing all the nutrients they need.
- Venison is a novel protein for many dogs, meaning they haven’t been exposed to it before, which reduces the likelihood of an allergic reaction. Venison is a lean, high-quality protein source that’s often used in hypoallergenic dog foods.
- Rabbit is another novel protein that’s less likely to cause an allergic reaction. Similar to venison, many dogs haven’t had prior exposure to rabbit, making it an excellent substitute for those with common protein allergies.
- Kangaroo is a less common protein found in dog food, making it a good option for dogs with food allergies. Kangaroo meat is lean, high in protein, and less likely to trigger allergies due to its novelty in most dogs’ diets.
- Sweet Potato is a common ingredient in hypoallergenic dog foods, too, and is generally well-tolerated by most dogs. It’s an excellent source of vitamins, minerals, and dietary fiber, making it a healthy carbohydrate for dogs with food sensitivities.
- Peas are a great source of protein and are usually well-tolerated by dogs. They’re often used in grain-free and hypoallergenic dog foods as a carbohydrate and protein source, providing essential nutrients without triggering allergies.
- Green Beans are often included in dog foods and treats due to their high nutritional value and general safety for most dogs. They’re low in calories and high in fiber, making them another excellent choice for dogs with food sensitivities.
- Duck is a novel protein that’s also less commonly used in dog foods. It’s often considered a great protein substitute for dogs with allergies to more common proteins like chicken or beef. Duck is rich in amino acids and it’s highly digestible.
- Bison is a novel protein that’s lean and nutrient-dense. It, too, is less likely to cause allergic reactions because many dogs have not been exposed to it. Bison is often a promising protein source for dogs with common protein allergies.
- Quinoa is a seed that’s often used as a grain substitute in hypoallergenic dog foods. It’s high in protein and fiber and it’s generally well-tolerated by dogs, making it another good option for dogs with sensitivities to common grains.
- Pumpkin is a nutritious ingredient that’s high in fiber and beneficial to digestion. It’s often included in dog foods to support gastrointestinal health and it’s generally safe for dogs with food sensitivities.
It’s important to note that every dog is different, and what works for one dog may not work for another.
Hypoallergenic Dog Food
In addition to safer foods, there are some highly recommended hypoallergenic dog foods on the market that are known for their high quality and effectiveness at managing dog food allergies and sensitivities. Each of these brands have multiple food options to choose from.
- Hill’s Prescription Diet
This is a specialized prescription diet that contains hydrolyzed protein. Hydrolyzed protein is protein that’s been broken down into smaller pieces to minimize the risk of triggering an allergic reaction in dogs with food sensitivities. - Royal Canin Veterinary Diet

Most of these hypoallergenic dog food options are available without a prescription, but it’s always a good idea to consult with a veterinarian before making any major changes to a dog’s diet, especially if they have known allergies or sensitivities. A trusted vet can help to choose the best option for a dog’s specific needs.
Medicinal Options
When it comes to managing allergies and the relentless itching they cause in dogs, two popular medicinal treatments available are Cytopoint and Apoquel. While both are effective, they work in different ways and are suited for different situations.
Cytopoint and Apoquel are primarily formulated to tackle the itching and inflammation associated with atopic dermatitis, which is an allergy to environmental factors like pollen, dust, or mold. However, they can also provide relief for symptoms related to food allergies, particularly itching.
It’s important to note, though, that these medications do not address the underlying cause of food allergies, which is the dog’s immune system reacting to specific food proteins. They won’t “cure” a dog of allergies.
Cytopoint
Cytopoint is a monoclonal antibody that targets and neutralizes a protein called interleukin-31 (IL-31), responsible for causing itchiness in dogs. Administered as a painless injection under the skin every 4 to 8 weeks, Cytopoint is especially useful for dogs suffering from both atopic dermatitis and food allergies. It’s considered safe for long-term use and it can be used alongside other medications.
- Effectiveness: Cytopoint helps relieve itching by specifically targeting and neutralizing the IL-31 protein.
- Use: Primarily used for atopic dermatitis but can also relieve itching caused by food allergies.
- Administration: Given as an injection every 4 to 8 weeks.
Cytopoint for dogs is often considered when traditional treatments like antihistamines or steroids fail to provide relief or cause undesirable side effects.
Apoquel
Apoquel (oclacitinib) is an oral medication that inhibits Janus kinase (JAK) enzymes, which play a role in the itch response. Apoquel starts working within 4 hours and provides relief for about 24 hours. It’s effective for managing atopic dermatitis and environmental allergies and it’s usually given twice daily for the first 14 days, then once daily thereafter. Apoquel is also considered safe for long-term use but it should be used with caution in dogs with certain health conditions.
- Effectiveness: Apoquel reduces itching and inflammation by inhibiting JAK enzymes.
- Use: Effective for both atopic dermatitis and food allergies.
- Administration: Oral medication, typically given daily.
Apoquel for dogs serves as a good alternative to steroids and antihistamines, particularly for dogs that don’t respond well to these medications.
Both treatments are generally well-tolerated, but it’s important to consult with a veterinarian to determine the best option for a dog’s specific condition and health status. As stated earlier, while Cytopoint and Apoquel can alleviate the itching and discomfort associated with food allergies, the most effective way to manage food allergies is to identify and eliminate the allergenic food from a dog’s diet. This can be achieved through an elimination diet and careful monitoring, under the guidance of a veterinarian.
Keeping Dog Food Allergies and Sensitivities at Bay
Navigating dog food allergies and sensitivities can be tough, but knowing the causes and how to handle them can greatly improve a dog’s life. Like people, dogs can develop allergies to different foods, causing issues like skin irritations and stomach problems.
Dogs can get these allergies at any time of their life when their immune system wrongly sees certain proteins as dangers. This leads to symptoms like itching, swelling, and digestive troubles. To prevent and manage allergies, we need to slowly introduce new foods, watch for reactions, and work with our vet to find and avoid specific allergens.
Now you know 10 Common Dog Food Allergies, including beef, chicken, dairy, and wheat, and you know that recognizing these triggers will help us make better choices for a dog’s diet. We also identified Common Dog Food Sensitivities, which are different from allergies as they usually involve trouble digesting certain ingredients rather than immune reactions.
Some dog breeds are more likely to have food allergies because of their genetics. Knowledge concerning Breeds With Higher Risk of Food Allergies helps us take all necessary steps to manage and prevent allergies for these dogs.
For safer food options, some ingredients are less likely to cause problems—ingredients like venison, rabbit, and sweet potato. You’re now aware of some Safe(r) Food Choices that are a good place to start for dogs with food sensitivities or allergies.
If a dog needs a special diet, you now have Hypoallergenic Dog Food options that use fewer ingredients and unique proteins to lower the chance of allergies.
You also know of Medicinal Options like Cytopoint and Apoquel, which can help with itching and swelling linked to environmental and food allergies. While these treatments help ease symptoms, the best way to manage food allergies is to identify and remove the allergenic food from a dog’s diet by monitoring closely and trying an elimination diet.
The bottom line is that by being informed, being proactive and working closely with a veterinarian, we can help our dogs live happy, healthy lives without the discomfort of food allergies and sensitivities.
