My Border Collie, Fairley, is the smartest dog, but she's always getting into things and I can't trust her outside of her crate unless I'm right there. Does anyone have any tips for games or activities that would tire her out kind of quickly? I'm going to start going to college this August, so I won't have the time to work her out for hours. Also, she likes to learn and knows a lot of tricks. She knows stay, but are there any other commands that I could teach her that would give me more control? Another problem is that she's also mouthy. I have a feeling this is because she's in her crate for too long. If this is the case, any tips for tiring her out should mostly solve this problem. When she's in her crate I give her a regular Kong and stuff it with cheese or peanut butter, but she tires of them quickly. I really don't want to have to get rid of her, but if things stay the same I might have to. It stresses me out when I have to worry about watching her every second. Please help!
