As pet parents, staying alert to anything that can negatively affect our furry friends’ well-being is critical. While many of us consider our pets’ dietary requirements, we may overlook the potential lurking danger: food allergies. Like us, even our four-legged friends can be allergic to some types of food. To protect your pet from such unpleasant experiences, you must know which foods could trigger pet allergies. Read on to find out more.

Identifying Food Allergies in Pets

Before we delve into what foods can trigger pet allergies, we must clearly understand how these allergies manifest in pets.

  • Skin Irritation: Food allergies often lead to skin problems in pets. Itchy skin, known as pruritus, is a frequent symptom. Pets may scratch, lick, or chew at their skin excessively to relieve the itching, resulting in redness, hair loss, and skin lesions. The irritation can occur in different body areas, including the face, ears, paws, belly, and tail.
  • Gastrointestinal Issues: Digestive problems are another hallmark of pet food allergies. Pets may experience vomiting, diarrhea, and sometimes, increased flatulence (gas). Stomach discomfort is common, and symptoms can vary from intermittent to persistent.
  • Ear Infections: Food allergies can contribute to the development of ear infections in pets. Allergies cause inflammation in the ear canal, leading to irritation and an increased risk of bacterial or yeast infections. Pets may shake their heads or scratch their ears in response to the discomfort.
  • Chronic Ear Inflammation: Besides ear infections, food allergies can lead to chronic ear inflammation, even without evident infection. Pets may have recurring ear issues, with persistent redness and swelling in the ear canal.
  • Skin Infections (Pyoderma): Constant scratching and chewing due to food allergies can break the skin, making it susceptible to bacterial infections. Pets with food allergies may develop pyoderma, a bacterial skin infection requiring veterinary treatment.
  • Anal Gland Problems: Food allergies can sometimes lead to anal gland issues in pets. Pets may scoot their bottoms on the floor or exhibit defecation discomfort due to inflamed or impacted anal glands.
  • Respiratory Signs (Rare): In rare cases, food allergies in pets may cause respiratory symptoms, such as sneezing or nasal discharge. However, respiratory signs are less common than skin and gastrointestinal symptoms.

At this point, you might be curious to find out more information about pet allergies in general. Alongside food allergies, environmental dust, mold, or pollen allergies can also trigger pet reactions. Similarly, pets could exhibit allergies to certain chemicals, materials, and even some insects. Regular wellness vet exams can help in the early detection and effective management of these conditions.

Foods That Trigger Allergies in Pets

Foods That May Trigger Allergies in Dogs

  • Beef: Beef is a common dog allergen. Some dogs may develop allergic reactions to proteins found in beef.
  • Dairy Products: Dairy products, such as milk, cheese, and yogurt, can cause dog allergies. Many dogs are lactose intolerant, which can lead to gastrointestinal issues.
  • Wheat: Wheat and other grains containing gluten are potential allergens for some dogs. Gluten sensitivity can lead to skin problems and digestive disturbances.
  • Chicken: While chicken is a common ingredient in many dog foods, some dogs may be allergic to chicken proteins, leading to skin irritation and digestive issues.
  • Eggs: Eggs are a source of high-quality protein, but some dogs may have allergic reactions to egg proteins.
  • Soy: Soy-based ingredients can trigger dog allergies, resulting in skin problems and gastrointestinal discomfort.
  • Corn: Corn is another grain some dogs may be allergic to. Corn allergies can manifest as skin irritation and digestive disturbances.
  • Artificial Additives: Some dogs may be sensitive to artificial additives and preservatives in commercial pet foods.

Foods That May Trigger Allergies in Cats

  • Fish: Fish, especially common types like salmon and tuna, can be allergenic to some cats, leading to skin or gastrointestinal problems.
  • Beef: Beef is also a potential allergen for cats. Cats may develop allergic reactions to beef proteins.
  • Dairy Products: Like dogs, many cats are lactose intolerant, and dairy products can lead to digestive issues.
  • Wheat: Cats may also have sensitivities to wheat and gluten-containing grains, causing skin problems or gastrointestinal disturbances.
  • Chicken: Although chicken is a popular ingredient in cat food, some cats may be allergic to chicken proteins.
  • Corn: Corn is another potential cat allergen, causing skin irritation and digestive discomfort.
  • Soy: Soy-based ingredients may trigger cat allergies, resulting in skin problems or gastrointestinal issues.

Individual Variability

  • It’s essential to recognize that every pet is unique, and their sensitivities to certain foods can vary. Some pets may have severe allergies to specific ingredients, while others may tolerate the same foods without issues. 
  • Identifying food allergies in pets often involves conducting food trials or elimination diets under the guidance of a veterinarian.

If your pet exhibits an adverse reaction to a particular food type, getting a check up for dogs and cats at a trusted vet is recommended. It’s important to note that these symptoms can also indicate other health conditions.

Are Pet Food Labels Helping?

When choosing pet food, carefully read the labels to identify potential allergens and select products specifically formulated for your pet’s needs. If you suspect your pet has food allergies, consult a veterinarian for proper diagnosis and guidance on selecting an appropriate diet that avoids triggering allergens. A tailored diet can help manage allergies and improve your pet’s health and well-being.

The Role of a Balanced Diet

Maintaining a balanced diet for your pet can significantly reduce the risk of food allergies. Ensure your pet’s diet consists of foods that are naturally less likely to cause allergic reactions. These include foods like lamb, rabbit, or venison, which are often used as alternatives for pets allergic to chicken or beef.

Besides keeping an eye on your pet’s diet, consider the importance of maintaining oral health. It might surprise you, but neglecting pet dental care can lead to several health issues, including allergies. Carbohydrate-rich diets often lead to poor oral health, which eventually might result in gum diseases and other related conditions that exacerbate pet food allergies.


If you suspect your pet is suffering from a food allergy, it’s advisable to seek professional help immediately. A thorough history of your pet’s dietary intake can help your vet identify possible allergens. Remember, allergens can hide in the most unexpected places, but with knowledge, vigilance, and regular wellness vet exams, you can help your pet lead a healthy and allergen-free life.
