Lice are small insects that live on the skin of dogs. They spend their entire lives living among the hairs and do not survive well off the host. Lice are also very host specific – dogs do not get lice from other animals and dog lice do not infest other animals. Infestations are very contagious and can be spread by contaminated objects (brushes, bedding, toys). Lice feed on either skin scales and secretions or blood. Clinical signs are itching, skin flaking, and scabs that usually occur on the head, neck, and back. Although very small, both adults and nits (small, white eggs attached to hair shafts) are readily visible. Treatment is successful with most topical insecticides (shampoo, dip, spray) that are approved for puppies. All animals in contact should be treated and any bedding cleaned thoroughly. Retreatment is necessary in 2 weeks. Special bathing products (available in the pharmacy section of stores) and a fine comb will be necessary to remove the nits (eggs) that are glued to the hair shafts.
