Life Cycle of Lice in Dogs

Lice have a relatively simple life cycle compared to other parasites. They do not jump or fly; they primarily spread through direct contact between infested and noninfested animals. The life cycle of lice consists of several stages that revolve around their development and reproduction. There, lice are species specific three main stages: eggs (nits), nymphs, and adults.

Eggs (Nits)

Female lice lay eggs, called nits, which are usually attached to the dog’s hair shafts near the skin. Nits are oval and small, often white or yellowish in color. They are firmly glued to the hair shaft, and can be challenging to remove. Nits take about a week to hatch.

Nymphs

 Once the nits hatch, they release nymphs. Nymphs resemble smaller versions of adult lice and undergo a series of molts as they develop into adults. This process typically takes a few weeks.

Adult Lice

 Nymphs mature into adult lice. Adult lice are larger and capable of reproduction. They continue the cycle by laying eggs on the host’s hair, perpetuating the infestation.
