I had one once. Sweetest dog in the world. She wanted to herd all the other animals and keep an eye on them. So much innate knowledge. My folks were visiting and I let her out, she was watching a cat near the road and the meanest man in the neighborhood purposely hit her. Shattered her pelvis. My Dad and I chased that guy down and he came out with a rifle at us. It was just a horrible experience. We raced her to the vet and then paid $1000.00 to fly her to Portland, Oregon to a special vet. The prognosis was bleak and I ended up putting her down.
Her name was Muffie and she was used to having scrambled eggs every morning so I just kept that up. Now I have 4 house cats, no dogs. Just too heart breaking.
Keep her away from roads. They consider the traffic to be an intrusion of their territory and they won't get out of the way.
