Well, it looks like the knee injury/surgery finally spoiled that boy to the 'unth' degree.
After finishing his rehab here and subsequent slow(?4 week back to normal?) HA, routine, he has decided that the routine he had of going out the back door (only 1step) vs. out the front (5 steps) is more fun. He's worse than a kid.

He's now sitting on back step, gets excited about something, barks to come in, turns around in circles, wants a small stick rawhide bone, with bone in mouth runs to front door to go out and jumps on sofa. Then he decides it's time for his 'biscuit' and barks to come in, runs to back door, does his version of jumping up and down, he gets his biscuit and wants out back to eat it. He tries to do this off and on all day to try and get more treats, but I only give him his big pig ear bone and at end of day give him one more small rawhide bone for his last treat. He's an absolute NUT!
One good thing about this fun routine for him is that he does get exercise running through the house from door to door.

That's My Bernie!!!
