While a Furminator tends to be expensive compared to a regular dog brush, they are well worth the money.
When I sell one, I always tell my customer to prepare a big plastic bag when they use it on their dog to gather all the hair that comes off.
Usually I see them a few days later to thank me for the advice as they spend way less time cleaning up the loose hair behind their dogs.
I also use a Furminator on my three bassets. It helps a lot.
