Signs Your Dog Might Have a Food Allergy & What to Do

Just like humans, our canine companions can develop allergies to certain foods. Watching your dog scratch endlessly or deal with an upset stomach can be incredibly frustrating, especially when you are not sure what is causing it.

Food allergies in dogs occur when their immune system overreacts to a specific protein in their diet. Here is a guide to spotting the signs of a food allergy and the steps you should take to help your furry friend.

1. Recognize the Common Symptoms

Unlike humans who often experience respiratory issues with allergies, dogs typically show allergic reactions through their skin and digestive system. Watch out for:

• Chronic Itching: Constant scratching, licking, or biting, especially around the paws, face, ears, and belly.
• Frequent Ear Infections: If you are constantly treating your dog for ear infections, a food allergy could be the hidden culprit.
• Gastrointestinal Issues: Recurring vomiting, diarrhea, or excessive gas after eating.

2. Know the Most Common Allergens

It is a common misconception that grains are the primary cause of allergies in dogs. In reality, the most common allergens are usually the main protein sources.
According to veterinary dermatologists, the top offenders are beef, dairy, wheat, chicken, and lamb.

3. The Elimination Diet (The Gold Standard)

If you suspect a food allergy, the most effective way to diagnose it is through an elimination diet, guided by your veterinarian.
This involves feeding your dog a completely new, hypoallergenic diet (using a novel protein like venison or rabbit, or a hydrolyzed protein prescription diet) for 8 to 12 weeks. During this time, your dog cannot have any other treats, table scraps, or flavored medications.

4. Reintroducing Foods

If your dog’s symptoms improve on the elimination diet, the next step is to slowly reintroduce their old food to see if the symptoms return. This confirms the allergy. From there, you can work with your vet to find a long-term diet that keeps your dog healthy and itch-free.

Frequently Asked Questions (FAQ)

Can a dog suddenly become allergic to a food they have eaten for years?
Yes! In fact, most dogs develop food allergies to ingredients they have been eating consistently for a long time. The immune system suddenly decides to recognize the familiar ingredient as a threat.

Conclusion
Dealing with a dog’s food allergy requires patience, as diagnosing the exact cause takes time. However, by paying close attention to their symptoms and working closely with your veterinarian, you can find the right diet and bring your dog much-needed relief.
