1. **Excessive Scratching and Biting**: If your dog is scratching or biting at their skin more than usual, it could be a sign of flea irritation. Pay attention to areas like the base of the tail, behind the ears, and under the armpits, as these are common hotspots for fleas.
2. **Red or Irritated Skin**: Flea bites can cause allergic reactions in some dogs, leading to redness, inflammation, or even hot spots. If you notice any signs of irritation, it’s worth investigating further.
3. **Flea Dirt**: Flea dirt looks like small black specks on your dog's skin or fur. This is actually flea feces, which is digested blood. You can check for flea dirt by parting your dog's fur and looking closely, or by brushing your dog over a white surface to see if any black specks fall off.
4. **Hair Loss**: If your dog is losing patches of fur, especially in areas that they are scratching or biting, it could be due to flea infestations. This can lead to bald spots or thinning fur.
5. **Restlessness or Irritability**: Dogs with fleas may become restless and irritable due to discomfort. If your usually calm dog seems anxious or unable to relax, fleas might be the cause.
6. **Flea Eggs**: Flea eggs are tiny, white, and oval-shaped. They can often be found in your dog’s fur or in areas where your dog sleeps. They are harder to spot than fleas themselves, but if you see them, it’s a clear sign of an infestation.
7. **Behavioral Changes**: Some dogs may become more withdrawn or exhibit changes in behavior when they are uncomfortable due to fleas. Keep an eye on any sudden changes in your dog’s demeanor.
If you suspect your dog has fleas, it's essential to consult with your veterinarian for proper diagnosis and treatment options, including topical treatments, oral medications, and environmental control measures to eliminate fleas from your home.
