1. **Itchy Skin**: One of the most common signs of food allergies is excessive itching. Dogs may scratch, chew, or lick their skin, particularly around the face, ears, paws, and belly.
2. **Ear Infections**: Frequent ear infections or inflammation can be a sign of food allergies. Symptoms may include redness, swelling, and a foul odor from the ears.
3. **Digestive Issues**: Dogs may experience vomiting, diarrhea, or flatulence due to food allergies. These symptoms can occur shortly after eating or may be chronic.
4. **Skin Rashes or Hives**: Allergic reactions can cause rashes or hives on the skin, which may appear as red bumps or welts.
5. **Swollen Face**: Some dogs may have swelling around their eyes, ears, or muzzle, which can indicate an allergic reaction.
6. **Weight Loss**: If a dog is not absorbing nutrients properly due to food allergies, it may lead to weight loss or lack of appetite.
If you suspect your dog has a food allergy, it’s crucial to consult with a veterinarian for proper diagnosis and treatment. They may recommend an elimination diet to identify the specific allergen. Keep in mind that food allergies can develop at any age, so even if your dog has been eating the same food for years, they can still develop an allergy.
For example, if your dog suddenly starts scratching more than usual or has recurring ear infections, it may be time to investigate their diet and consider a change to a hypoallergenic food.
