I don't understand why the last people could not get her house trained. She knows where the door is and wakes me up when she needs to go out. Yes she is still a puppy, so accidents will happen, but it has been very easy to get her house trained.
There are really only 2 things that need to be worked on besides basic puppy training. Car chasing and nipping. Which are collie traits. Great. :p The nipping thing I am slowly working on, but I think the chasing issue will take a long time to correct. We try to get her to sit when we see a car, and then wait. But as soon as the car goes by she moves as if to chase it. If the car if going in the same direction as us on a walk, I can sometimes get her to ignore it with a command, but on the whole she wants to chase the cars. And herd them :p :/ And while I am sure she would be very happy if she caught one, I don't think the driver would be happy with a punctured tire :p I am going to look into puppy obedience classes, but they might have to wait until she is spayed.
And a video of her chasing her tail. She did this the first day we had her, and while its cute, not something I want to encourage (lots of walking and playing help her stop)
