I agree! I know some Yorkies require less exercise but mine starts to go zonkers in the evening( just as I am winding down) if she hasn't had enough exercise. So I try and walk mine everyday late afternoon to take that edge off and it definitely helps. If I can't walk her, I let her chase the ball back and forth for at least an hour. If not- at 10:00 pm she grabs the ball and starts barking as to say," Ok, I am ready to play
