I hav'nt seen the ad, but I use a dremel on my dogs. I'm not sure if you'd want to try it on your Rottie, if she/he is full grown. They do make quite a noise, and I don't know how your dog responds to getting his nails trimmed, but I had to get both of mine done by the vet, because I could'nt hold them, plus the male was so adverse to it, he would growl.
Thanks for the reply. The noise was my main concern, so you hit the nail on the head. My rottie hates to have his nails cut. I literally have to sit on him. He isn't aggressive at all; he just try to pull his foot away and run to his crate. You can tell he wants to bite the clippers but won't because he is afraid of getting me in the process.
My fox terrier hates having his nails clipped so I tried the dremel, he likes it better than the cutters, but he is still nervous. My corgi is afraid of the vibration, so cutting is easier. I used it on my mom's big dog and she liked it.
Trying out a dremel with a sanding barrel is cheaper than buying a new gadgit. ( assuming that you already own the dremel)
are we talking about the electric rotary tool or the rechargeable? most of my dogs didn't like the noise of the electric but were fine with the quieter battery powered one. I start all puppies on it and also use it on all the rescued dogs. So many of the rescues don't like having their nails done because some one has cut them too short using clippers. once they find out they aren't going to be hurt they usually relax and i have actually had a few sleep thru having nails done and ears cleaned.i like how smooth the nails are after using the sandpaper bands.i haven't seen the new tool but it would have to be really great and cheap for me to replace what i have now.
I not sure how much rotaries usually cost, but this one is $30 for a small and $50 for the larger more powerful model. It has a cover on the top so it catches the filings. It looks cool but I'm reluctant to by off TV.
