If you’re dog is sneezing or has watery eyes, you might be wondering – are dog food allergies common?
It is estimated that around 10% of dogs suffer from food allergies, making it a prevalent issue.
Food allergies occur when a dog’s immune system reacts to a specific protein or ingredient in their food.
The immune system sees the protein as a threat and releases antibodies to fight it, leading to an allergic reaction.
Understanding dog food allergies can be challenging, as the symptoms can be similar to other health issues.
Some common symptoms of dog food allergies include itching, skin rashes, vomiting, diarrhea, and ear infections.
These symptoms can be mild or severe, depending on the severity of the allergy.
Identifying the allergen in dog food can be challenging, as dogs can develop allergies to any protein or ingredient in their food.

Understanding Dog Food Allergies
Food allergies in dogs are not as common as environmental allergies such as flea/tick allergies or seasonal allergies.
However, they can still affect some dogs, with only 0.2% of dogs being affected by food allergies, according to PetMD [1].
A food allergy is an adverse immune response to a particular protein in the dog’s diet.
When the dog’s immune system identifies an allergen as a foreign substance, it produces antibodies to fight it.
The immune response can cause inflammation and damage to the dog’s body tissues, leading to symptoms such as itching, skin infections, hives, diarrhea, vomiting, weight loss, and even seizure disorders in rare cases [1].
The allergens that commonly cause food allergies in dogs are proteins found in beef, dairy, wheat, chicken, egg, lamb, soy, pork, rabbit, and fish [2].
However, any food ingredient can potentially trigger a food allergy in a dog.
Diagnosing food allergies in dogs can be tricky and requires a thorough examination by a veterinarian.
The vet may recommend a food elimination trial, where the dog is fed a novel protein source that it has never eaten before, such as venison or duck, for several weeks.
If the dog’s symptoms improve during the trial, the vet may then reintroduce the original diet to see if the symptoms return [2].
It is important to note that food intolerance is different from a food allergy.
Food intolerance occurs when a dog has difficulty digesting a particular food, leading to gastrointestinal symptoms such as vomiting or diarrhea.
However, food intolerance does not involve the immune system and is not life-threatening [3].

Common Symptoms of Dog Food Allergies
Food allergies in dogs can cause a range of symptoms, many of which can be mistaken for other conditions.
Here are some of the most common symptoms of dog food allergies:
Itchy Skin
Dogs with food allergies often experience itchy skin, which can lead to scratching, biting, and licking.
This can cause hair loss, redness, and skin infections. Itchy paws, hot spots, and skin rashes are also common.
Digestive Issues
Vomiting and diarrhea are common symptoms of food allergies in dogs.
These symptoms can be caused by an allergic reaction to a specific ingredient in the dog’s food. In some cases, the dog may also experience stomach pain and discomfort.
Sneezing and Runny Eyes
In some dogs, food allergies can cause respiratory symptoms like sneezing and runny eyes.
These symptoms are more commonly associated with environmental allergies, but can also be caused by food allergies.
Swelling
Swelling is a less common symptom of dog food allergies, but can occur in severe cases.
Swelling can occur in the face, throat, and other parts of the body, and can be life-threatening if not treated promptly.
If your dog is exhibiting any of these symptoms, it’s important to consult with a veterinarian to determine the underlying cause and develop an appropriate treatment plan.
In many cases, dietary changes can help manage symptoms and improve your dog’s quality of life.
Identifying Allergens in Dog Food
Food allergies in dogs are quite common and can cause a variety of symptoms.
Identifying allergens in dog food can be tricky, but it is essential to help manage your dog’s symptoms.
Some of the most common allergens in dog food include beef, dairy, wheat, chicken, soy, fish, lamb, egg, rabbit, pork, corn, and rice.
Proteins are often the culprit, but any ingredient can cause an allergic reaction.
The most accurate method of diagnosing a food allergy in dogs is through an elimination diet or food trial.
During this trial, the dog is fed a special hypoallergenic diet for eight to twelve weeks. This diet must not contain any ingredients that the dog has eaten in the past.
If the dog’s symptoms improve during this time, it is likely that they have a food allergy.
It is important to note that an elimination diet must be followed strictly, as even a small amount of the allergen can cause symptoms to reappear.
After the trial period, the vet may recommend reintroducing certain foods one at a time to determine which specific ingredient is causing the allergy.
When reading dog food labels, it is important to look for specific ingredients that your dog may be allergic to.
Some manufacturers may use vague terms like “meat” or “animal by-products,” which can make it difficult to determine the exact ingredients in the food.
Another option is to have your veterinarian perform a food allergy test. This involves a blood test or skin prick test to identify specific antibodies that indicate a food allergy.
However, these tests are not always accurate and may not identify all allergens.
Again, identifying allergens in dog food can be challenging, but it is essential to help manage your dog’s symptoms.
Conducting an elimination diet or having a food allergy test performed by your veterinarian can help identify specific allergens.
When reading dog food labels, look for specific ingredients to avoid potential allergens.
Treatment and Management of Dog Food Allergies
If a dog is diagnosed with a food allergy, the most effective treatment is to avoid the allergen completely.
This can be achieved through a variety of methods, including medication, veterinary diets, and avoidance.
Medication
Antihistamines and corticosteroids may be prescribed by a veterinarian to reduce the symptoms of a food allergy in dogs.
However, it is important to note that these medications only provide temporary relief and do not address the underlying cause of the allergy.
Veterinary Diet
A veterinary diet is a specially formulated dog food that is designed to exclude the allergen that is causing the food allergy.
These diets may contain novel proteins or hydrolyzed protein, which are proteins that have been broken down into smaller pieces that are less likely to trigger an immune response.
It is important to note that these diets should only be fed under the supervision of a veterinarian.
Prescription Diet
In some cases, a dog may require a prescription diet that is tailored to their specific needs.
These diets may contain a combination of novel proteins, hydrolyzed protein, and other ingredients that are safe for dogs with food allergies.
Avoidance
The best way to manage a food allergy in dogs is to avoid the allergen altogether. This may require reading labels carefully and avoiding certain ingredients, such as chicken, beef, dairy, or wheat.
It is also important to avoid feeding table scraps or any other foods that may contain the allergen.
Dog Breeds Prone to Food Allergies
While any dog can develop a food allergy, some breeds are more prone to them than others.
According to PetMD, Labrador Retrievers, Golden Retrievers, English Springer Spaniels, Cocker Spaniels, Collies, Miniature Schnauzers, and Shar-Pei are more likely to develop food allergies.
Cocker Spaniels, in particular, are known to have a higher incidence of food allergies than other breeds. They are commonly allergic to beef, chicken, and dairy products.
Retrievers, German Shepherds, and West Highland White Terriers are also prone to food allergies, with chicken and beef being the most common allergens.
It’s important to note that just because a breed is more prone to food allergies doesn’t mean that every dog of that breed will develop one.
Similarly, dogs of breeds that are not typically prone to food allergies can still develop them.
Difference Between Food Allergies and Food Intolerance – Are Dog Food Allergies Common?
It is important to understand the difference between food allergies and food intolerance in dogs.
While the symptoms of both conditions may be similar, the underlying causes are different.
Food allergies in dogs are caused by an immune system reaction to certain proteins found in their food.
This reaction can cause a range of symptoms, including skin rashes, itching, and gastrointestinal issues.
According to PetMD, the most common symptoms of food allergies in dogs show up as reactions in their skin. Skin problems are common in dogs with food allergies.
On the other hand, food intolerance in dogs is caused by an inability to properly digest certain ingredients in their food.
This can lead to symptoms such as vomiting, diarrhea, and flatulence. Unlike food allergies, food intolerance does not involve the immune system.
It is important to note that while food allergies and food intolerance are different conditions, they can both cause similar symptoms in dogs.
This can make it difficult to determine the underlying cause of a dog’s symptoms.
According to BeChewy, one way to differentiate between food allergies and food intolerance is to think of a food allergy as a hypersensitivity reaction, which means the animal has been exposed to the allergen previously.
In contrast, food intolerance does not require previous exposure to the offending ingredient.
Overall, while food allergies and food intolerance are different conditions with different underlying causes, they can both cause similar symptoms in dogs.
It is important to work with a veterinarian to properly diagnose and treat any food-related issues in dogs.
Role of Nutrition in Managing Dog Food Allergies
Proper nutrition is essential for managing dog food allergies.
Pet food containing limited ingredients can help to identify the allergen and prevent further allergic reactions.
A limited-ingredient diet is formulated to exclude common allergens such as beef, chicken, wheat, and soy.
This diet contains a single protein source and a single carbohydrate source to reduce the risk of allergic reactions.
It is important to note that not all dogs with food allergies will respond to limited-ingredient diets.
Some may require a novel protein diet, which contains a protein source that the dog has never been exposed to before.
In addition to limited-ingredient or novel protein diets, there are also prescription diets available that are formulated to manage food allergies in dogs.
These diets are typically available only through a veterinarian and may require a prescription.
Supplements can also play a role in managing dog food allergies. Omega-3 fatty acids, for example, can help to reduce inflammation and improve skin health.
Probiotics can also be beneficial in improving gut health and reducing the risk of allergic reactions.
Common Misconceptions About Dog Food Allergies
There are many misconceptions surrounding dog food allergies. Here are a few of the most common ones:
Misconception #1: Food allergies are the most common type of allergy in dogs
Contrary to popular belief, food allergies are not the most common type of allergy in dogs.
In fact, only 0.2% of dogs are actually affected by food allergies, while environmental allergies, such as seasonal allergies and flea/tick allergies, are much more common.
Misconception #2: Allergic reactions to food always manifest in the digestive system
While it is true that digestive issues, such as vomiting and diarrhea, can be a sign of a food allergy, they are not always present.
In fact, many dogs with food allergies experience symptoms in other parts of their body, such as their skin, ears, and paws.
Misconception #3: Gas is a sign of a food allergy
While excessive gas can be a sign of a food allergy, it is not always present. Gas can be caused by a variety of factors, including diet, stress, and certain medical conditions.
Misconception #4: Yeast infections are always caused by a food allergy
While a food allergy can contribute to the development of a yeast infection, it is not always the cause.
Yeast infections can be caused by a variety of factors, including allergies, hormonal imbalances, and certain medical conditions.
Misconception #5: A dog with a food allergy will always show immediate signs of an allergic reaction
While some dogs with food allergies do show immediate signs of an allergic reaction, such as hives and swelling, others may not show any signs for several hours or even days after consuming the allergen.
This delayed reaction can make it difficult to identify the offending food.
