My cousin was telling me that his dog Tasha chases neighborhood cats. He said that, back when she was still a puppy, they saw a stray cat and said, "go get it, Tasha", and that was the end of that. They didn't mean for her to become a cat-chaser. I guess they just didn't think.
It's a shame because I'd like for them to come to my house and bring Tasha, but I have two cats. Unfortunately, I don't think that would be a good scene.
