1. **Itching and Scratching**: One of the most noticeable signs is excessive itching. Dogs may scratch, bite, or chew at their skin, leading to redness and irritation.
2. **Skin Irritation**: You may notice rashes, hot spots, or flaky skin. Allergies can cause inflammation, leading to red patches or bumps on the skin.
3. **Ear Infections**: Allergies can lead to recurring ear infections. Symptoms may include shaking of the head, scratching at the ears, or a foul odor coming from the ears.
4. **Respiratory Issues**: Some dogs may develop a runny nose, sneezing, or coughing due to allergies. This is more common with airborne allergens like pollen.
5. **Gastrointestinal Problems**: Allergies can also affect your dog's stomach, leading to symptoms such as vomiting or diarrhea, especially with food allergies.
6. **Watery Eyes**: If your dog has allergies, they may have watery or red eyes, similar to how humans react to allergens.
If you notice any of these signs, it's important to consult with your veterinarian. They can help identify the cause of the allergies and recommend appropriate treatment, which may include dietary changes, medications, or allergy testing. Keeping a diary of your dog's symptoms can also be helpful for your vet in determining the cause of the allergies.
Preventative measures, such as regular grooming and maintaining a clean living environment, can also help minimize exposure to allergens.
