Those are great brushes! Yeah, the vet actually gives you a lesson before you get the brush, because, you can actually "cut" you pet if you comb too hard. EEEK. For those interested, if you have a Petco, and take the time to fill out their free membership cards that they have, I found out (after I spent $60 at the vet. LOL) that you can get the exact same brush there for half of the price with their card discount at times. Check it out. Even without the card, it is less than at the vets and it is the exact same brush!
