1. **Itching and Scratching**: One of the most noticeable signs is excessive scratching or biting at the skin. Dogs may scratch so much that they create sores or hot spots.
2. **Redness and Inflammation**: The skin may appear red and inflamed, particularly in areas where the dog has been scratching or biting.
3. **Rash or Hives**: Allergies can lead to the development of rashes or hives on the skin, which may be raised and itchy.
4. **Dry, Flaky Skin**: Allergies can cause the skin to become dry and flaky, leading to dandruff-like flakes.
5. **Ear Infections**: Dogs with skin allergies often experience recurrent ear infections, which may be accompanied by shaking of the head or scratching at the ears.
6. **Swollen Paws**: Allergies may cause swelling in the paws, leading to licking or chewing at the feet.
7. **Hair Loss**: In some cases, dogs may experience patchy hair loss due to constant scratching or inflammation.
8. **Odor**: A foul smell may develop due to secondary infections that can occur with skin allergies.
If you notice any of these symptoms, 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 alleviate your dog's discomfort.
