How to Dremel Dog Nails @ DoberDawn.com
The above link is a very good instruction page on using the dremel tool on your furbabies nails. About the best I've seen and has pictures for viewing as well.

The dremel in the picture looks like the rechargeable cordless.
I recommend the electric variety. The only advantage of the rechargeable cordless dremel, it will shut off if hair becomes entangled in the sanding drum.
Battery varieties do not have the power of the elect., plus battery life is short lived. You need two batteries if you go the rechargeable route. Extra or replacement batteries cost almost as much as a new dremel. That's why I went with the elect.
The elect. you have to shut it off should you get hair entangled in the appliance. You have to really be on guard using the elect. for this reason. A dog could jerk or move suddenly, placing long hair in harms way.
It just takes practice and getting used to. Once you do, its a piece of cake. And remember to run the elect. on the lower speeds.
