1. **Excessive Scratching and Grooming**: One of the most noticeable signs is if your dog is scratching more than usual or grooming themselves excessively. This behavior is often a response to the irritation caused by flea bites.
2. **Red or Irritated Skin**: Check for any redness, inflammation, or hot spots on your dog’s skin, particularly around the neck, tail, and belly areas. Fleas can cause allergic reactions in some dogs, leading to these symptoms.
3. **Flea Dirt**: Flea dirt, which looks like small black specks (similar to pepper), can often be found on your dog’s skin or in their bedding. To confirm, you can place some of these specks on a wet paper towel; if they turn red, it indicates blood and confirms the presence of fleas.
4. **Hair Loss**: If your dog is losing hair in patches, especially in areas where they scratch or bite frequently, this could be a sign of flea infestation.
5. **Restlessness or Irritability**: Dogs may become restless or irritable due to the discomfort caused by fleas, leading to changes in behavior.
6. **Flea Bites on Humans**: If you notice small, itchy red bumps on your skin, especially around your ankles, it could indicate that your dog has fleas, as these pests often jump onto humans as well.
If you suspect your dog has fleas, it’s important to act quickly. Consult with your veterinarian for appropriate treatment options, which may include topical treatments, oral medications, or flea collars. Additionally, ensure to treat your home and yard to prevent re-infestation.
