Just like us, our dogs can face some trouble with the food they eat. Understanding food allergies is key to keeping our furry pals happy and healthy. In this guide, we’re going to explore the ins and outs of food allergy in dogs – what to watch out for, why it happens, and how we can help our canine buddies live their best lives without the hassle of allergies. So, buckle up as we dive into the basics of food allergies in dogs, making sure we’re all in the know for the well-being of our four-legged friends.
What is a Food Allergy in Dogs?
A food allergy in dogs occurs when their immune system reacts to an allergen in their food. This reaction is not immediately evident when they sample a cuisine for the first time; instead, it develops over a longer period. Contrary to popular belief, genuine food allergies in most dogs are to a specific protein rather than grains. However, dogs can also develop allergies to any component of their diet.
When a dog is allergic to a specific food and encounters that particular meal, its immune system attacks the protein it perceives as alien. This often leads to symptoms like swelling, redness, and itching. Food allergies are less common than environmental allergies, such as flea/tick allergies and seasonal allergies. Only 0.2% of dogs are affected by dietary allergies.
Symptoms of Food Allergies in Dogs
The symptoms we identify as related to a food allergy are caused by inflammation of the respiratory system, intestines, skin, and/or eyes. Dogs may exhibit one or more of these symptoms, and the manifestation can vary widely between individual pets. Each dog is unique, so even when facing the same problem, the symptoms in two different pets may be similar or distinct.
Some of the most common signs of food allergies in dogs are :
- Skin-related symptoms include itching, such as licking, scratching, biting, and rubbing on the face, paws, back, limbs, bum, and ears.
- Redness can be observed on the skin and ears.
- Dry skin may manifest as increased dandruff.
- Oily skin and hair coat can occur.
- Ear-related symptoms involve repeated infections and inflammation.
- Grooming behaviors, like excessive grooming in cats or any self-grooming in dogs, may increase.
- Hot spots (eczema) may develop on the skin.
- Hair loss can be noticeable.
- Gastrointestinal issues may include soft stool, diarrhea, vomiting, and gas.
- Increased frequency of bowel movements may occur.
- Eye-related symptoms consist of watery eyes or other eye discharge, redness of eyes, sneezing or reverse sneezing.
- Swelling of eyes or face may be observed.
These symptoms vary among individual pets, and recognizing them is crucial for addressing potential food allergies in dogs.
Causes of Food Allergies in Dogs
Dogs commonly develop allergies to proteins, with dairy, meat, chicken, chicken eggs, soy, and wheat gluten being frequent culprits. When a pet allergic to any of these ingredients consumes food containing them, antigens and antibodies interact, leading to the onset of symptoms. It’s essential to note that allergies can stem from nearly any dietary item. While proteins are the most common triggers, other substances and additives in the diet may also cause allergic reactions.

How is a food allergy diagnosed?
Identifying food allergies in dogs typically involves a combination of physical examinations, observation of clinical symptoms, and the dog’s response to food trials. If your dog’s veterinarian suspects a food allergy, they may recommend a carefully monitored food trial. It is crucial to strictly follow the prescribed guidelines for the food trial, which usually lasts eight to twelve weeks. Avoid giving treats or other diets during this period, as they could influence the trial’s results.
Various methods can be employed when conducting a food trial to pinpoint the specific allergen affecting the dog:
- A prescription hydrolyzed protein diet. To prevent the proteins in these diets from binding to receptors and triggering an immune response, they have been broken down into tiny particles.
- An elimination diet: These diets can either be home-cooked under a veterinarian’s supervision or formulated by a veterinary nutritionist. They feature a single source of protein and/or carbohydrates.
Elimination diets serve as a primary tool for identifying food allergies, but they are not suitable for long-term nutrition. Your veterinarian will discuss whether this type of testing can aid in diagnosing your pet’s condition. However, evidence suggests that food trials are a more effective means of testing than blood testing.

How is a food allergy treated?
After identifying the problematic food substance, a diet devoid of that ingredient is selected. Modern veterinary care offers several hypoallergenic diets that can be fed to your dog for the remainder of their life. These hypoallergenic diets fall into three categories:
Veterinary hydrolyzed protein diet, in which the protein molecules are broken down to a size too small to be recognized by your dog’s immune system
Veterinary novel protein diet that does not contain any products that were present in your dog’s previous foods
Home-prepared novel protein diet that does not contain any ingredients that were present in your dog’s previous diets (must be formulated by a veterinary nutritionist and typically requires the addition of a balancing supplement)
Your veterinarian will prescribe the best option specific to your dog’s needs.
In addition to any necessary lifestyle modifications, your dog’s veterinarian may recommend allergy relief medication. This medication will assist in managing the symptoms of the allergic reaction, including itching and addressing any secondary skin infections that may have arisen from the irritant.
Can food allergies be cured?
Dogs with food allergies cannot be cured; the sole course of therapy is avoidance. While a hypoallergenic diet may effectively control symptoms in most pets, some dogs may require medication during severe instances.
Although there is no cure for food allergies, pet owners can effectively control them over time with the right diet and by avoiding allergenic substances. If your dog has a food allergy, pay extra attention to the labels on the dog food you give it, especially when it comes to treats, to avoid giving it anything it shouldn’t have.
Conclusion
Understanding your pet’s food allergy may require some time and patience, but the payoff is a more comfortable and joyful life that your furry companion will thank you for! With the support of your veterinarian, this diagnostic and transitional period can be made as effortless as possible for your four-legged friend!
What is the most common source of food allergies in dogs?
The primary culprit for food allergies in dogs is typically protein.
Do all dog breeds have the potential to develop allergies?
Yes, all breeds of dogs, regardless of age, have the potential to develop allergies. However, certain breeds are more predisposed to food allergies. Labrador Retrievers, Golden Retrievers, English Springer Spaniels, Cocker Spaniels, Collies, Miniature Schnauzers, and Shar-Pei breeds are particularly prone to food allergies.
What are the usual indications of food allergies in dogs?
Typical signs of food allergies in dogs include itching, recurrent skin and ear infections, and the tendency to chew or lick their feet.
Is it possible for my dog to develop additional food allergies?
Dogs that have developed an allergy to a specific food might be susceptible to other food-related allergies in the future. Additionally, many dogs with food allergies may also have other allergic conditions like atopy (inhalant or environmental allergy) or a flea allergy. If you suspect your pet may be dealing with a food allergy, consult your veterinarian for guidance on improving your pet’s overall well-being and comfort.
