How Quickly Can Fleas Infest a Dog?

Fleas infest dogs in a variety of ways, including through the use of your pet’s fur. Adult fleas can be up to an eighth of an inch long, have a flat body, and have large back legs. They can jump as high as twelve inches and carry up to one hundred immature fleas. They will leave specks of blood on your pet’s fur, which will eventually turn brown.

Fleas usually develop from an egg to an adult within 15 days. But, in some circumstances, they can live for up to a year. Fleas lay their eggs on your pet and land on its fur. A female flea can lay up to 50 eggs per day. The eggs will hatch in about two to five days, and the adult flea will grow to be about one eighth of an inch long. They will then feed for about two weeks. Later, they will form cocoons and pupate. The pupa will stay in a host for up to twelve months.

Fleas may also be brought into your home by humans. If you live in an area with long grasses or woods, you are likely to have fleas. Likewise, rugs, plush toys, and bedding can harbor fleas. Therefore, it is important to check for any fleas before you bring your pet home. If you can, wash all of these items in hot water.
