“I bought this dremel after my dog trainer used hers on my puppies nails. Before I had used a regular dog nail trimmer on her nails and they were still kinda long and extremely sharp. My dog trainer used the dremel on my 13 week old puppies nails and after only a few minutes my puppy just laid in her arms and actually began to fall asleep while her nails were being done.

When they were finished they were SO short and smooth. The dremel did NOT cause her to bleed or cause her any pain once so ever. I decided to buy one for myself and used it on my 2 LARGE dogs myself and it did great! SUPER pleased with how the dremel did and how my dogs nails look now vs with the nail trimmer!”

“I don’t like spending time in nail salon’s, so I do my own. My previous Dremel battery died and can’t be replaced as I have had it for approx 15 years. Love the new one and still able to use my old attachments for the new one. Would recommend this product and seller for future purchases. Fast shipping and great pricing”
