We used to use a mobile dog groomer for our Alfie, but he was a little bugger and used to go for her, so we tried giving him some Bachs Rescue Remedy about an hour or so before she arrived and the difference was really noticeable. Unfortunately she gave up to have a baby and in the meantime, my DD trained as a groomer and she has her own mobile business now so she does him, he's still as nippy as ever, but she doesn't stand any nonsense, he needs to be muzzled to do his feet, but will just about tolerate everything else.
