Fleas and dogs have a parasite host relationship. What happens to the fleas in a home when another dog is brought into the home?

When another dog is brought into a home, the fleas already present in the home may begin to infest the new dog. Fleas are adept at jumping from one host to another, so they can easily transfer from one dog to another. This can result in the new dog becoming infested with fleas, causing itching, irritation, and potentially spreading diseases.

In some cases, the increased number of hosts in the home may also lead to a larger flea population overall. This can make it more challenging to control and eradicate the fleas from the home.

It is important to regularly check pets for fleas, treat them with appropriate flea prevention products, and take measures to eliminate fleas from the home to prevent infestations and protect the health of both pets and humans.
