Chester hasn't gotten used to it and I've been cutting his nails once a week for 4 1/2 years! He squirms and wiggles like a greased pig. Can't get the grinder anywhere near him, either. Open the drawer we keep it in and he's out the pet door!
Millie on the other hand doesn't mind too much and she lets me use the grinder. She's so much easier to do things to.

babolaypo65 - I can totally understand the screaming thing. My Westie used to do that, too! I'd pick up the trimmers and then go to pick up his paw and he'd scream bloody murder! Very un-nerving to me and the neighbors!
