Just after I wrote my previous post in this thread I got inspired to work on the long nails of a foster dog I just took in (temporarily) last night.

Morgan is the largest dog we've had and he likes to use his teeth - he 'mouths' things but he's always very gentle. I figured trimming his nails would be a good way to find out how much restraint he has.
Well, I learned that he doesn't like having his paws held and he was pretty much terrified by the sound of the grinder. I ended up with him in our walk-in shower, trying to make him comfortable. It wasn't going well.
I tried 'fake grinding' his nails with the grinder off. That eventually went alright. Then I tried running the grinder and then touching the handle to his body, legs and paws. His paws were still sensitive but he tolerated the rest, for the most part. I wanted to make sure that I did not grind either of us while doing this so I finally removed the sanding head. It was much quieter then. (This B&D model only has two speeds.) He tolerated it even more.
Then I was able to put the collet up against his nails. I did that for quite awhile and then I put the sanding head back on. He let me do his dewclaws - no problemo. What a difference from the dance we were doing at first! I did other nails that were off the floor because of the way he was sitting but he wouldn't let me lift his paws to trim.
I wouldn't have been so tolerant of all of this resistance with my dogs. I'm becoming 'kinder and gentler' in my old age and having a dog this big is especially good incentive to work *with* the dog! I like it.
BTW, although Morgan mouthed the grinder a few times and brushed against me a couple times, he never showed anything close to agression in this very stressful situation. What a great guy! Please tell me if you know someone who would like a great dog like this. (I'm in Indiana but would fly him anywhere around here.)
