Food allergies are uncommon in dogs. However, when they do strike the symptoms can be concerning for both us and our canine companions. Today, our Orange Park veterinary dermatologist lists the best types of foods to help alleviate your dog's food allergy symptoms.
Food Allergies in Dogs
Since dogs can't tell us whether they are suffering from a sensitivity to an ingredient in their food or a food allergy, it's important to beware of the most common symptoms of food allergies and what to do if your dog is diagnosed with a food allergy.
Signs & Symptoms of Food Allergies in Dogs
Food allergies in dogs often start to become an issue as the dog reaches their first birthday. That said, dogs of any age can develop sensitivities and allergies.
The most common signs and symptoms of food allergies in dogs include:
- Vomiting
- Diarrhea
- Gassiness
- Red, irritated skin
- Rashes on ears and feet
- Itching
Some of these symptoms may be spotted by owners or during a routine exam by your regular veterinarian. If you're concerned your dog may have an allergy, we encourage you to schedule a preliminary examination with Animal Friends Dermatology
Common Causes of Food Allergies in Dogs
Plant-based or animal ingredients in food have proteins that can cause food allergies. Common culprits are wheat, dairy, beef and corn. While it may seem counterintuitive, it can take a fairly long time for symptoms of food allergies to become apparent. It's not unusual for a dog to become allergic to a food that they have been eating for many months.
How Dogs are Diagnosed with Food Allergies
An elimination diet is the only reliable method of diagnosing food allergies in dogs.
If your vet thinks your dog may be suffering from a food allergy, he or she will prescribe a specially formulated hypoallergenic dog food for your pet. For a minimum of 8 to 10 weeks, you'll only feed your dog the prescribed food in order to discern whether the change in diet helps to alleviate your dog's symptoms.
It's essential that your dog eats only the hypoallergenic food while they are on this elimination diet. (Unfortunately, this means no sneaking them the odd treat). This special 10-week diet will help your dog's body to adapt to the food and give your vet the opportunity to assess your dog's overall health.
If your dog's symptoms are alleviated or disappear while they're on the elimination diet, your vet may ask you to return to feeding your dog their original diet. If original symptoms return, then your vet can be confident in diagnosing your dog with a food allergy.
The Best Foods for Dogs with Allergies
Prescription Dog Food
If your dog's food allergy symptoms are severe, your vet may recommend that you feed your dog a prescription dog food. While this option can be pricey, novel protein and hydrolyzed diets available by prescription only are typically superior to those that can be purchased over the counter.
Grain-Free Dog Food
If your pet has a sensitivity to corn, wheat and other grains a grain-free dog food may be ideal. These foods have the added benefit of also being gluten-free.
Limited Ingredient Dog Foods
Limited ingredient dog foods address the presence of allergens by including just one protein source, (such as beef, lamb or chicken), often combined with just a single carbohydrate source. When 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.
Novel Ingredient Dog Food
Novel ingredient dog foods replace traditional dog food proteins such as beef and chicken with more unusual proteins such as salmon, duck, or venison. Many novel ingredient dog foods also use unusual carbohydrates such as sweet potatoes to help balance out the diet.
After your dog is diagnosed, your vet will work with you to find the best diet for your dog. Many food options are available to help alleviate your dog's food allergy symptoms.
