1. **Itching and Scratching**: One of the most noticeable signs is persistent itching. Dogs may scratch, bite, or lick their skin excessively, which can lead to hair loss and skin damage.
2. **Red or Inflamed Skin**: Allergies can cause inflammation, leading to red patches on the skin. You may notice areas that look irritated or swollen.
3. **Hot Spots**: These are localized areas of inflamed skin that can become infected if the dog continues to scratch or bite at them. They often appear as moist, red lesions.
4. **Dry or Flaky Skin**: Allergies can cause the skin to become dry and flaky, leading to dandruff-like flakes in the dog's coat.
5. **Ear Infections**: Dogs with skin allergies may also suffer from recurrent ear infections, which can cause itching, redness, and a foul odor in the ears.
6. **Paw Licking**: If your dog is licking their paws excessively, it may be a sign of allergies. This behavior can lead to inflamed or discolored paws.
7. **Swelling**: Some dogs may experience swelling in their face, particularly around the eyes or muzzle, due to allergic reactions.
8. **Changes in Coat Condition**: Allergies can lead to changes in the dog's coat, such as dullness, shedding, or patchy areas of hair loss.
If you notice any of these signs, it's important to consult with your veterinarian. They can help diagnose the specific cause of the allergy and recommend appropriate treatments, which may include antihistamines, corticosteroids, or dietary changes. Regular grooming and maintaining a clean environment can also help minimize allergens in your dog's surroundings.
