How Many Fleas Are on a Dog?

It is difficult to tell how many fleas are on a pet, especially if it is an adult dog. Some animals can react strongly to flea saliva, leading to an intense allergic reaction and continual scratching. Other pets may be oblivious to the presence of fleas and only scratch out of annoyance. A heavy infestation of fleas can lead to blood loss, especially in puppies.

It is best to visit a veterinarian to learn about the right flea control methods. While flea products are great for the initial kill, you should be aware that their residual effect may not be as effective. It is important to treat your dog’s yard in addition to his body, so that he doesn’t become infested again.

One of the first signs of a flea infestation is scratching and itching. Seeing one flea on a dog isn’t necessarily an indicator of an infestation, but it’s certainly enough to start treating the animal immediately. A few fleas on a dog can be a sign of many more hiding deep in the fur of your pet.

Adult fleas reproduce quickly. Adult fleas are about one-eighth inch long and brown to black. They live for three weeks during the peak season and can live for up to 100 days on their host.
