They're infamous climbers. If you just sit on the couch and partially stretch your legs out in front of you, you'll probably see that lil puppy climbing up them.
They'd make great mountain goats!
I was going to say to be sure not to leave a collar or harness on her when you are not there in order to prevent it from being caught when she is climbing like that and hanging herself.
If you put a top on it, please be sure it is not something her little paws can be caught in.
