Do fleas have a preference for long hair or short hair when it comes to finding a host to infest?

Fleas generally do not have a strong preference for long or short hair when it comes to choosing a host. They are primarily attracted to warmth, movement, and carbon dioxide, which all animals produce. However, fleas might be more easily visible and accessible in shorter hair because they can move and feed on the skin more easily. On the other hand, long hair can provide more hiding spots for fleas, making it harder to spot them, but it doesn’t necessarily make long-haired pets more prone to infestations. Fleas infest based on the host's presence rather than hair length.
