1. **Itching and Scratching**: One of the most noticeable signs is excessive scratching, biting, or licking of the skin, particularly around the tail, back, and belly. Dogs may scratch so much that they cause skin irritation or infections.
2. **Red or Inflamed Skin**: Allergic reactions often lead to redness and inflammation of the skin, especially in areas where the dog bites or scratches frequently.
3. **Hot Spots**: These are localized areas of skin inflammation that can become infected. They often appear as red, moist, and painful patches.
4. **Hair Loss**: Dogs may experience hair loss in patches due to constant scratching or biting at their skin. This can lead to bald spots, particularly around the ears, neck, and tail.
5. **Flea Dirt**: You might notice small black specks (flea dirt) in your dog's fur, which are actually flea feces. You can check for this by brushing your dog over a white surface; if you see black specks that turn red when wet, it's flea dirt.
6. **Skin Infections**: Secondary bacterial infections can occur due to the constant scratching and can manifest as pus-filled bumps or sores.
7. **Behavioral Changes**: Dogs with flea allergies may become more irritable or anxious due to discomfort. You might notice changes in their sleeping patterns or increased restlessness.
If you suspect your dog has a flea allergy, it's essential to consult your veterinarian for a proper diagnosis and treatment plan. They may recommend flea control products, antihistamines, or other medications to alleviate your dog's symptoms and prevent future infestations.
