Chair Claiming

I am concerned that this might be a genetic defect, do you have a cure for him laying claim to this chair?

Gryph playing “snow attack” after the horses have been fed. It use to take us about an hour or so to take care of the horses each morning and each evening. Now, if it snows our routine goes-feed horses (while Gryph eats his chicken and plays in his kennel)-shovel snow with Gryph, plow snow with Gryph, bring in wood with Gryph and finally but not least play, play, play in the snow with Gryph which takes about three hours (if we keep things moving along). We get in the house in time for what has to be considered brunch!! You can’t help but love his enthusiasm.
