The Most Common Food Allergens in Dogs (And What to Watch For)
At Tobey Crafted, we’re on a mission to take the guesswork out of treating your pup right—especially when it comes to food allergies. If your dog is constantly itching, licking, or having stomach issues, the problem might be in their bowl.
Food allergies in dogs are more common than most owners realize, and they often show up in ways you wouldn’t immediately connect to food. Below are the top culprits behind canine food allergies—and how to spot them.
1. Beef
Beef is one of the most common proteins in commercial dog food—and one of the top triggers of allergic reactions. Because dogs are often fed beef-based meals over long periods, they’re more likely to develop a sensitivity to it over time.
Typical symptoms:
- Itchy skin (especially ears and paws)
- Chronic ear infections
- Hot spots or skin infections
- Digestive issues like vomiting or diarrhea
2. Dairy
Many dogs are lactose intolerant, but dairy can also trigger a true allergy. It’s often hidden in treats, supplements, or processed food.
Typical symptoms
- Itchy skin
- Red or inflamed ears
- Gas and Bloating
- Diarrhea
3. Chicken
Chicken is everywhere in dog foods and treats. And like beef, overexposure may lead to allergies or sensitivities, especially if the chicken isn’t high quality.
Typical symptoms:
- Persistent scratching
- Facial swelling
- Skin rashes or lesions
- Paw chewing
4. Wheat
Wheat can trigger allergic reactions in some dogs, especially those with gluten sensitivities. It’s a common filler in lower-quality dog foods.
Typical symptoms:
- Chronic ear infections
- Itchy, flaky skin
- Hair loss
- Gastrointestinal distress
5. Eggs
While eggs are a great protein source for many dogs, others can develop an allergy to the proteins in the yolk or white.
Typical symptoms:
- Skin irritation
- Stomach upset
- Respiratory issues (sneezing, wheezing)
6. Soy
Soy is a less obvious ingredient but still a known allergen in dogs. It’s commonly used as a plant-based protein in dog foods.
Typical symptoms:
- Excessive licking
- Skin inflammation
- Flatulence
- Poor coat quality
7. Lamb
Lamb was once considered a hypoallergenic option, but its popularity has changed that. Dogs can and do develop allergies to lamb, especially if it’s a primary protein in their diet.
Typical symptoms:
- Repeated ear infections
- Red, itchy skin
- Digestive upset
How to Know If It’s a Food Allergy
Food allergies often mimic other conditions, so diagnosis can take time. A vet may recommend an elimination diet—removing all potential allergens, then reintroducing foods one at a time to identify the trigger. This process can take 8–12 weeks but is the gold standard for food allergy diagnosis.
According to the American Kennel Club, food allergies make up about 10% of all allergies in dogs, but they’re frequently overlooked because the symptoms overlap with environmental allergies and infections.
