I look after a Chocolate Labrador three days a week and when his owners are away so he spends almost as much time with me as he does at home.
A while back, he was recovering from a leg operation and needed hydrotherapy which involved walking on a treadmill in a water tank, the idea being that it strengthens the limbs without putting too much of a load on the joints.
I took him to the local veterinary centre for this therapy and while I know him to be a clever and wise old boy, I wasn't prepared for what happened.
He entered the tank, the water was let in and the treadmill was started.
Finding the prospect of exercise a bit too much like hard work, he managed to straddle the moving belt and parked his paws on the non-moving edges.
After some persuasion, he reluctantly agreed to follow the rules.
