Lice are parasites that live on the skin of an affected dog. They are actually a small insect that feeds by chewing on the skin of the dog or by sucking the blood, depending on the type of louse.

Both types of lice can be passed directly from one dog to another through direct contact or through contact with contaminated objects, such as or bedding.

There are a wide variety of shampoos, as well as insecticidal sprays and powders that are effective in killing lice.  It may be necessary to treat your dog more than once to kill the developing nits as they hatch.

You can purchase lice treatments from your vet.
