Food Allergies in Dogs
If you believe that your dog is suffering from food allergies or sensitivity to an ingredient in their usual food, it's important to find out what the problematic ingredient is to remove it from its diet while still maintaining optimum nutrition.
Signs & Symptoms of Food Allergies in Dogs
Food allergies and sensitivities often don't appear until the dog reaches their first birthday, although they can develop in dogs of any age.
If your dog is displaying any of the following symptoms it may be suffering from a food allergy and should be examined by your veterinarian to determine the root cause of the symptom:
- Itching
- Red irritated skin
- Rashes on the ears and feet
- Gassiness
- Vomiting
- Diarrhea
Common Causes of Food Allergies in Dogs
Often in dogs with food sensitivities, proteins from animal or plant-based ingredients in the diet are the cause. Beef, corn, dairy, and wheat are some of the most problematic ingredients.
It may seem counterintuitive, but it can take a long time for symptoms of food allergies to become apparent. Often dogs appear to 'suddenly' become allergic to a food that they have been eating for months.
Diagnosing Your Dogs Food Allergies
After a thorough examination, if your veterinarian believes that your dog may be suffering from the effects of a food allergy or food sensitivity they will likely recommend beginning your dog on an elimination diet.
Elimination Diet for Dogs With Food Allergies
A specially formulated hypoallergenic food will be prescribed if an elimination diet is recommended for your dog. For 8-10 weeks you will only feed your dog the prescribed food, eliminating all other food sources from your pet's diet.
If one or more of the ingredients in your dog's regular food is the source of the symptoms, the elimination of the regular dog food should help to improve your dog's condition.
It's important to note that, for the elimination diet to work you must stop giving your dog treats during this period as well as their regular food. Only hypoallergenic food should be fed to your dog while they are on the elimination diet.
Being on the elimination diet for 10 weeks will allow your dog's body to adjust to the new prescription food and allow your veterinarian to assess your dog's overall health.
If the allergy symptoms clear up while your dog is on the elimination diet, your veterinarian may request that you return to feeding your dog their original diet to see if the allergy symptoms reappear.
While an elimination diet can help determine food allergies in dogs, other tests can also be useful, and provide quick results.
Best Foods for Dogs with Allergies
Following the diagnosis of food allergies, your veterinarian will work with you to determine the best diet and treatment plan for your dog. There are several dry food options available, to help alleviate food allergy symptoms in dogs.
Prescription Dog Food
If your dog's food allergy symptoms are severe, your veterinarian may recommend that you feed your dog a prescription dry food. While this option can be expensive, novel protein and hydrolyzed diets available by prescription are typically superior to those that can be purchased through pet supply stores.
Sticking to a prescribed diet may help your dog to stay healthy and comfortably free of allergy symptoms. Some of the prescription foods your veterinarian may recommend for dogs with food sensitivities include:
- Canine Hydrolyzed Protein Small Dog Dry Dog Food
- Hill's Prescription Diet® d/d Canine Potato & Venison Formula
- Purina Pro Plan FOCUS Adult Sensitive Skin & Stomach Salmon & Rice Formula
- Hill's Prescription Diet® Dog i/d® Sensitive Dry
Limited Ingredient Dog Foods
Limited-ingredient dog foods address the presence of allergens by including just a single protein source, (such as beef, lamb, or chicken), often combined with just a single carbohydrate.
When you are shopping for limited-ingredient dog foods it's important to check for a seal of approval from the Association of American Feed Control (AAFCO), as well as a "complete and balanced" claim from the manufacturer.
Limited ingredient foods that your veterinarian may recommend include:
- Purina Pro Plan Veterinary Diets HA Hydrolyzed Formula Chicken Flavor Dry Dog Food
- Hill's® Prescription Diet® d/d® Canine Skin Support Potato & Salmon Formula
- Nutro Limited Ingredient Diet Adult Dog Food - Natural, Salmon & Lentils, Grain Free, Non-GMO
- CANIDAE® PURE® Dog Food - Limited Ingredient, Natural, Grain Free, Chicken
Novel Ingredient Dog Food
Novel ingredient dry foods replace traditional dog food proteins such as beef and chicken with more unusual proteins such as venison, salmon, or duck.
Novel ingredients in dog foods may also include unusual carbohydrates such as sweet potatoes to help balance out the diet. Your veterinarian may recommend a novel ingredient in dog food such as:
- Purina Pro Plan FOCUS Adult Sensitive Skin & Stomach Salmon & Rice Formula
- Hill's Prescription Diet® d/d Canine Potato & Venison Formula
- CANIDAE® PURE® Dog Food - Limited Ingredient, Natural, Grain Free, Duck
- Nutro Adult Dog Food - Natural, Limited Ingredient, Duck & Lentils, Grain Free, Non-GMO
Grain-Free Dog Food
If your dog is found to have a sensitivity to corn, wheat, or other grains, grain-free dog food may be recommended. These foods have the added benefit of also being gluten-free. Some of the grain-free foods that your veterinarian may recommend include:
- Hill's Science Diet® Adult Sensitive Stomach & Skin Grain Free dog food.
- Purina Pro Plan Savor Adult Dog Food - Turkey & Chicken, Grain Free
- Science Diet® Adult Grain-Free Dog Food
- Nutro Limited Ingredient Diet Dog Food - Natural, Lamb & Sweet Potato, Grain Free, Non-GMO
