1. **Itching and Scratching**: One of the most noticeable signs of skin allergies is excessive itching. Your dog may scratch, bite, or lick their skin more than usual, which can lead to further irritation and even infections.
2. **Red or Inflamed Skin**: Look for areas of redness or swelling, particularly on the belly, paws, ears, and face. This inflammation can result from constant scratching or licking.
3. **Hot Spots**: These are localized areas of inflammation and infection that can develop from excessive licking or scratching. They often appear as red, moist, and painful patches on the skin.
4. **Rash or Hives**: Allergies can cause rashes or hives, which may look like small bumps or welts on the skin. These can be itchy and uncomfortable for your dog.
5. **Hair Loss**: Allergic reactions can lead to patchy hair loss, especially in areas where your dog is scratching or licking frequently.
6. **Ear Infections**: Dogs with skin allergies may also suffer from recurrent ear infections. Signs include shaking their head, scratching at their ears, or a foul odor coming from the ear.
7. **Changes in Behavior**: If your dog seems more irritable, restless, or anxious than usual, it could be due to discomfort from allergies.
If you notice any of these signs, it’s crucial to consult your veterinarian. They can help determine the cause of the allergies, whether it's environmental, food-related, or due to parasites, and recommend appropriate treatments or management strategies.
