1. **Excessive Scratching**: If you notice your dog scratching or biting at their skin more than usual, it could be a sign of fleas. Fleas cause itching due to their bites, which can lead to irritation and discomfort.
2. **Red or Irritated Skin**: Look for signs of redness or inflammation on your dog’s skin, especially in areas like the belly, legs, and base of the tail. Flea bites can cause allergic reactions in some dogs, leading to dermatitis.
3. **Flea Dirt**: This is a tell-tale sign of fleas. Flea dirt looks like small black specks on your dog’s fur or in their bedding. If you see this, you can confirm it by placing a few specks on a damp paper towel; if they turn reddish-brown, it’s flea dirt (digested blood).
4. **Hair Loss**: Excessive scratching and biting can lead to hair loss in patches. You may notice bald spots or thinning fur, particularly around areas that your dog can easily reach.
5. **Restlessness or Irritability**: Fleas can make your dog uncomfortable, leading to restlessness. You might see them pacing or unable to settle down.
6. **Tapeworms**: If your dog has fleas, they can ingest them while grooming, leading to tapeworms. You may notice small, rice-like segments around your dog’s anus or in their feces.
7. **Behavior Changes**: Dogs may exhibit changes in behavior, such as increased anxiety or aggression, due to the discomfort caused by fleas.
If you suspect your dog has a flea infestation, it’s important to act quickly. Consult your veterinarian for appropriate flea treatments and preventative measures to ensure your dog stays healthy and comfortable.
