Flea infestations can be uncomfortable and harmful to dogs. Some common signs of flea infestation in dogs include excessive scratching, biting, or licking, especially around the tail, back, and hind legs. You may also notice red or irritated skin, hair loss, flea dirt (black specks) on the fur, and even small insects moving around in the fur. In severe cases, anemia can occur due to blood loss from flea feeding. It's important to regularly check your dog for fleas, especially during warmer months or if your dog has been in contact with other animals.
