Dogs naturally lose old or damaged hair by shedding. Shedding is a normal process for dogs, the amount and frequency of shedding all depends upon their health and breed and the season. During the winter, dogs develop a thick coat and in spring it has to come out. This is when you see lots of unwanted hair around the house or on you. The furminator deShedding tool will help you reduce the amount of loose hair from shedding! So, that means, less time cleaning and more time with your dog.
