we've been using this for years, bc PUGS SHED LIKE THERES NO TOMORROW! omg... never knew how much they shed before i got my baby. But I'd still get pugs bc they're precious! You get a pile of their fur with this furminator. I don't use it on her all the time, just once a while. There is endless hair you can go on for ages... But remember to be gentle with your dogs.
