3. **Ear Infections**: Recurring ear infections can be a sign of food allergies. Dogs may shake their heads or scratch at their ears, indicating discomfort.
- Example: If a dog has chronic ear infections, it may be worth investigating potential food allergies.
4. **Red or Watery Eyes**: Allergies can cause inflammation in the eyes, leading to redness or discharge.
- Example: A dog may have watery eyes and frequently rub its face with its paws.
5. **Behavioral Changes**: Dogs may become more irritable or anxious due to discomfort from allergies. They might also show signs of lethargy.
- Example: A normally playful dog may become withdrawn or less active.
If you suspect your dog has a food allergy, consult your veterinarian for an appropriate diagnosis and treatment plan. They may recommend an elimination diet to identify the specific allergen.
