1. **Itching and Scratching**: One of the most noticeable signs of allergies is persistent itching. Your dog may scratch, bite, or lick their skin excessively, leading to redness or irritation.
2. **Skin Infections**: Allergies can weaken the skin's barrier, making it prone to infections. If you notice pus-filled bumps, hot spots, or flaky skin, it may indicate an allergic reaction.
3. **Ear Infections**: Dogs with allergies often develop ear infections. Look for signs such as shaking their head, scratching at their ears, or a foul smell coming from the ear.
4. **Watery Eyes and Sneezing**: Allergies can affect your dog's eyes and nose, leading to watery eyes, redness, and sneezing. If your dog seems to have a constant runny nose, it could be a sign of an allergy.
5. **Digestive Issues**: Food allergies can cause gastrointestinal problems. Symptoms may include vomiting, diarrhea, or excessive gas.
6. **Change in Behavior**: If your dog seems more irritable, lethargic, or restless than usual, it could be due to discomfort from allergies.
If you suspect your dog has allergies, it’s essential to consult with a veterinarian. They can help identify the cause and recommend appropriate treatments, which may include antihistamines, dietary changes, or allergy testing.
