My girlfriend has a Border Collie who sheds non-stop. She has some other brushes, which I've tried, but they don't collect much hair. And after brushing the dog it still shed just as much. Enter the Furminator! Since the dog spends a fair amount of time at my house I was desperate to figure out how to stop her from covering my carpets in dog hair. I forget how, but I found the Furminator on Amazon and saw all the 5-star reviews so bought one right away. And it hasn't let me down. The dog seems to mind it less than the other brushes and it takes out a lot of her hair. She still sheds a bit but so much less than before. I like it so much I just bought a 2nd one for my girlfriend's house.
