Dogs can indeed get nits because they can get lice. Nits are the eggs of lice, and since dogs can have lice infestations, they can also have nits attached to their hair shafts. However, dogs do not get lice or nits from humans, as lice species are very host-specific. Dog lice live and reproduce only on dogs, and human lice live on humans only, so there is no cross-infestation between dogs and humans. Lice on dogs can cause itching, hair loss, and skin irritation. The lice eggs (nits) are glued to the dog's hair near the skin and can be difficult to remove. Treatment typically involves special shampoos and medications prescribed by a vet to eliminate both lice and nits. It's important to treat any other pets in close contact with the affected dog and clean their environment to prevent reinfestation. Severe infestations may lead to more serious health issues like anemia, especially in young or vulnerable dogs.
