Fleas are the most common external parasite found on dogs. Although fleas are more likely to be a problem during warm-weather months, they can also cause problems during cooler seasons due to their ability to continue their life cycle indoors.

What are the symptoms of fleas on your dog?

The first sign of fleas for many pet owners is their dog’s repeated itching, scratching and chewing. You may see fleas or flea dirt (feces) on your dog. A dog’s constant itching and scratching may lead to visible patches of hair loss and reddened, irritated skin. Although many dogs are very itchy and uncomfortable, some dogs may show no signs at all and fleas can be difficult to see. In addition to making your pet uncomfortable, fleas can also transmit other parasites, such as tapeworms, to a dog.
