I have a 110 lb Doberman and this product was not even close to being powerful enough for his nails.Dremel 761-03 7,000/14,000 RPM Cordless Pet Nail Grooming Rotary Tool. I was very disappointed since I chose it over purchasing the "pedicure" and other such products because of Dremel's reputation. I gave it away to someone with smaller dogs and hope they get some use out of it
