When Riley was much younger I used to give him a stag bar , he would chew on that while I brushed him on the floor, it wasnt easy THEN I got a grooming table, what a change. He has no room to move about on it,
I started off with smearing the odd bit of peanut butter/primula on the chrome arm of the table, which he would lick , it got less and longer between.
He know stands or sits on the table for 15 mins each day while I brush him.
You could start with putting him on a table at first, they really change then , I find it calms them down, plus they have no where to run off to.
