I've never seen that before. Maybe one of the groomers here can help you with it. I'd love to find out more about it too.

I use and love the zoom groom by kong. It works really well on all of my dogs, with the exception of Bitsy who I've never tried it on. I couldn't believe how much hair it got off of Nacey and Nova. I got one for my friend's border collie and it worked well on his hair type too. I also use it on my cats. The good think is it's only $7, and I know if you are unsatisfied with it PetSmart will refund you your money.
