Stripping or hand-stripping is the process of pulling the dead hair out of the coat of a non-shedding dog, either by using a stripping knife or the fingers.
A hard, wiry coat has a cycle where it starts growing and then sheds as it reaches maximum length.
Hand-stripping coordinates the shedding and makes room for a new coat to grow. Stripping is the proper grooming method for most terriers, and is required for show dogs of many hard-coated breeds.
The hair is removed with either a stripping knife or stripping stone, with the top coat removed to reveal the dense, soft undercoat.
If done correctly, the procedure is painless. Many dogs are reported to enjoy having their hair stripped, especially when they are introduced to it as puppies.
