1. **Excessive Scratching and Biting**: If you notice your dog scratching more than usual or biting at their skin, it could be a sign of fleas. Pay attention to areas like the base of the tail, belly, and behind the ears, as fleas often congregate in these spots.
2. **Flea Dirt**: Flea dirt looks like small black specks in your dog's fur. It's actually flea feces, which is made up of digested blood. To check for flea dirt, part your dog's fur and look closely. You can also place some of the specks on a wet paper towel; if it turns red, it's flea dirt.
3. **Skin Irritation or Hot Spots**: Fleas can cause allergic reactions in dogs, leading to red, inflamed skin or hot spots. If you see any unusual skin conditions, it’s worth investigating further.
4. **Hair Loss**: If your dog is losing fur or has patches of baldness, especially in areas where they scratch frequently, it could be due to flea infestations.
5. **Restlessness**: Dogs with fleas may seem restless or uncomfortable, often changing positions or pacing as they try to relieve the itching.
6. **Visible Fleas**: In severe cases, you may actually see fleas jumping through your dog's coat. They are small, quick, and can be hard to spot, but they are usually about the size of a pinhead.
If you suspect that your dog has fleas, it's important to act quickly. Consult your veterinarian for appropriate flea treatments and preventive measures to keep your dog and home flea-free.
