Bosley is funny, if my hubby gives him a treat often Bosley throws it, I can pick up the same treat and he will happily take it.
He will not take the same treat 2 days in a row, except for his night time cashew.
He is offended if he gets the same thing for dinner 2 nights in a row too LOL
HAHAHAHA @ Alison! SO very true.
All of mine can be food flingers, too. Maybe we should all enroll them as Quarterbacks or pitchers.
