You can get an attachment for a Dremmel drill to grind nails safely. I tried that, but our older pugs totally freaked and it got lost somewhere along the way so I never tried it with the 2 we have now.
I don't have anybody else do the pug's nails unless they are under anesthetic for whatever reason because of the fighting and both of the little black boys we had would/will try to bite. The first 1 I knew why. Somebody cut them WAY too short, he just had tiny little nubbins when we first got him and I know they hurt him badly. The pug boy we have now I have no idea why because they've never been cut too short. But I think it's just a pug thing overall because our girls didn't/don't like it either, they just weren't as bad as the 2 boys. Well, except for 1 girl because she loved to get her nails done and painted. She was a very pretty pug and she knew it and would flirt shamelessly with human men. Right after she would get her nails painted she would trot around and throw her feet out so daddy would notice her freshly painted nails. Her name was Circe and boy did she live up to it.
When we took our friend's half malamute, half golden retriever because he got transferred and wasn't sure what his living situation was going to be, first time I took her to vet the tech went to cut her nails and i thought she was going to take his hand off. She was a big girl, better part of 90 pounds. I could have killed jim for not warning me about that. She was the most friendly and happy go lucky dog we've ever had, but lordy don't try to cut her nails. It took me and craig both to cut her nails, him to calm her down with pets and talking to, as well as hold her head if necessary while I cut her nails.
