1. **Excessive Scratching or Grooming**: One of the most noticeable signs is when your dog starts scratching or biting at their skin more than usual. This can lead to hair loss and skin irritation.
2. **Red or Inflamed Skin**: Flea bites can cause allergic reactions, leading to redness, swelling, or even hot spots on the skin. You might notice patches of irritated skin, especially around the base of the tail, neck, and belly.
3. **Flea Dirt**: Flea dirt looks like small black specks, which are actually flea feces. You can check for flea dirt by running a comb through your dog’s fur or by placing a white paper towel under your dog while brushing. If you see red stains after wetting the black specks, it indicates flea dirt.
4. **Restlessness or Irritability**: Dogs may become restless or irritable due to the discomfort caused by fleas. They might have trouble settling down or sleeping.
5. **Hair Loss**: In areas where dogs scratch or bite excessively, you may notice patches of hair loss. This can occur in localized areas or be more widespread.
6. **Skin Infections**: If fleas are left untreated, the constant scratching can lead to skin infections, which may require veterinary attention.
7. **Visible Fleas**: Sometimes, you can actually see fleas jumping around in your dog’s fur, especially in areas with less fur, such as the belly or behind the ears.
If you suspect your dog has fleas, it's important to treat them promptly with appropriate flea treatments and consult your veterinarian for the best course of action. Regular flea prevention can also help keep your dog comfortable and healthy.
