Sasha loves to jump. It was quite by accident we found this out. She loves to play tug and we often do it. But, this heat has made it impossible in the evenings and frankly, I get bored with tug. So, I have a ball that I was trying to teach her to fetch. She wasn't really interested in chasing the ball and bringing it back. I decided to bounce it around to see if it would catch her interest. It did. However, about the 3rd time of bouncing it, she jumped up and caught it mid air. I was shocked!! Now, that's all she wants to do. Even outside with her tug, she wants to jump for it. I admit that she's really, really good at it but at 12 1/2 weeks old, it can't be good for her hips. I tried to redirect her but she ends up laying down and looking at me with those sad eyes. She jumped at her tug today while I was walking back to the door. I'm 5'3". She jumped at least that high. What should I do? She absolutely loves it but at the same time, I need to protect her. I'm conflicted.
