Food allergies are rather uncommon in dogs, but they can happen. When they do occur, the symptoms can be quite stressful for owners and their canine companions. Today, our Palmdale vets share the best dog foods for your pup if they have any allergies.
Food Allergies in Dogs
If you suspect that your dog is suffering from food allergies or sensitivity to an ingredient in their usual food, it's important to know what the most common symptoms of food allergies are, and what you should do if your dog is diagnosed with a food allergy.
Signs & Symptoms of Food Allergies in Dogs
Food allergies in dogs often begin to appear as the dog reaches their first birthday, although allergies and sensitivities can develop at any age.
The most common signs and symptoms of food allergies in dogs include:
- Gassiness
- Vomiting
- Diarrhea
- Itching
- Red irritated skin
- Rashes on the ears and feet
Common Causes of Food Allergies in Dogs
Proteins from animal or plant-based ingredients in the diet are most often the cause of dog allergies. Typically, beef, dairy, corn, and wheat are the most problematic foods for dogs. Although it may seem counterintuitive, it can take a fairly long time for the symptoms of food allergies to appear. It is not unusual for a dog to be allergic to a food that they have been eating for many months.
Diagnosing Your Dogs Food Allergies
The only real way to diagnose food allergies in dogs is through an elimination diet.
If your vet suspects that your dog is suffering from a food allergy, a specially formulated hypoallergenic dog food will be prescribed for your pet. For a minimum of 8-10 weeks, you will only feed your dog the prescribed food to gauge whether the change in diet helps to alleviate your dog's symptoms.
Only hypoallergenic food should be given to your dog while they are on the elimination diet. (Unfortunately, that means no sneaking in the odd treat). This special 10-week diet will allow your dog's body to adjust to the food and allow your vet to assess your dog's overall health.
If your dog's symptoms clear up while on the elimination diet, your vet may request that you return to feeding your dog their original diet. If original symptoms return then your vet can be confident that your dog has a food allergy.
Best Foods for Dogs with Allergies
Following the diagnosis, your vet will work with you to determine the best diet for your dog. Several food options are available to help alleviate your dog's allergy symptoms.
Prescription Dog Food
If your dog's food allergy symptoms are severe, your vet may recommend that you feed your dog 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
Just like the name suggests, grain-free foods and treats are ideal if your dog has a sensitivity to corn, wheat and other grains. These foods are also gluten-free, though be careful as it is not reciprocated — gluten-free dog foods aren't necessarily grain-free.
Novel Ingredient Dog Food
A novel ingredient dog food is one that scraps common proteins that can cause your pet's allergies to flare up — beef, chicken, etc. — and replaces them with duck, salmon or other less-common proteins that are new to your dog's system. Many limited ingredient foods will often use novel carbohydrates, leading to combinations like venison and potato.
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.
