Review (1/5): Doesn't cut.
My most recent special-needs dog came to me with some severe behavioral issues. She's doing much better now but still has an extreme reaction to any attempt at grooming, which is why I thought I'd give this a try. While she hates being brushed she's getting better with it so I thought this might be a sneaky way to do a little bit of trimming here and there.
Nope. These things do not cut. I grabbed one of my older, more tolerant dogs and tried to cut one of the knots out from under her armpit but this thing WOULD. NOT. CUT. Not at all. I tried both sides of it and even switched combs, to no avail. Finally gave up and got the scissors.
Attempted to gently brush another dog's tummy because she has much finer hair but it wouldn't even cut her little wispy hairs.
Just get a good pair of scissors and some doggy Xanax because these combs are not going to work.
