1. **Itching and Scratching**: One of the most noticeable signs is persistent itching, which may lead to excessive scratching, biting, or licking of the skin.
2. **Skin Irritation**: You may observe redness, swelling, or rashes on the skin. This can sometimes lead to hot spots, which are localized areas of inflamed skin.
3. **Ear Infections**: Dogs with allergies often suffer from recurring ear infections, which can cause symptoms such as shaking their head, scratching at their ears, and a foul odor coming from the ears.
4. **Watery Eyes and Sneezing**: Allergies can also affect the eyes, leading to watery eyes, redness, and sneezing, similar to hay fever in humans.
5. **Digestive Issues**: Some dogs may experience gastrointestinal symptoms like vomiting or diarrhea if they have food allergies.
6. **Changes in Behavior**: Allergic reactions can make dogs uncomfortable, leading to changes in their behavior, such as increased irritability or restlessness.
If you suspect your dog has allergies, it’s important to consult with a veterinarian for proper diagnosis and treatment options. They may recommend allergy testing, dietary changes, or medications to help manage your dog's symptoms.
