The Hammocks are used to take the weight of dogs being groomed. It is particularly good for short legged dogs ex. Shih-tzu, Scottie, Dachshund
Ideally if you are a lone groomer you should buy 2 extenders so you can easily take the weight of one side at a time.
Dogs can be lifted higher or just weight taken slightly off the table, whichever they prefer.
You can use the hammock in conjunction with other handling aids such as a groomers helper.
