1. **Itching and Scratching**: One of the most common signs of allergies in dogs is excessive scratching, licking, or biting at their skin. This can lead to redness, irritation, and even hot spots.
2. **Ear Infections**: Allergies often cause inflammation in the ears, leading to frequent ear infections. You might notice your dog shaking their head, scratching at their ears, or having a foul odor coming from them.
3. **Watery Eyes**: Allergies can cause your dog’s eyes to become watery or red. They may also squint or have a discharge from their eyes.
4. **Sneezing and Coughing**: Just like humans, dogs can exhibit respiratory symptoms. If your dog is sneezing, coughing, or showing signs of nasal discharge, it could be related to environmental allergens.
5. **Digestive Issues**: Food allergies can lead to gastrointestinal symptoms such as vomiting, diarrhea, or excessive gas. If you notice these symptoms after feeding your dog a particular food, it may be worth consulting your vet.
6. **Skin Infections**: Allergies can compromise your dog’s skin barrier, making them more susceptible to bacterial or fungal infections. Look for signs of redness, swelling, or pus-filled bumps.
If you notice any of these symptoms, it’s essential to consult with your veterinarian to determine the cause and appropriate treatment for your dog’s allergies. They may recommend allergy testing, dietary changes, or medications to alleviate your dog's discomfort.
