I remember with fondness trimming and FILING my English Setters nails while they SLEPT! They loved it. Higgins? NO WAY, JOSE! He is in constant motion and won't stand for any grooming, let alone nail trimming. Having said that, there are lots of Yorkies here who LOVE or at least tolerate grooming and nail trimming. It really depends on your puppy.
My advice? Find the very best groomer you can, a groomer who really loves little ones and has great patience. If I had it to do over again? I would take him for just a nice bath at the groomers. Then I'd take him a week later for a little trim and a treat, then the nails.....
But start by brushing him each day....once or twice.....and praising him.....Now I DID do this and it didn't help at all with Higgins.....sigh......
I hope you have one of the good ones.........
