My dog has allergies and tends to have problems with her skin so we try to keep her trimmed up. I thought I could use this grooming kit on her at home and save some money at the groomer. Nope. My did will not sit still for this. It seems to function fine. She just does not like the noise of it. I don’t want to ding the product over the fact that my dog is uncooperative. I will continue to attempt this on her in between grooming appointments to see if she can adjust to it, but for her for now, this is a no. My sister tried it on her dog and had no problem whatsoever. I think it is just going to depend on the personality of the dog.
