My best dogs have come from the pound... of course I've only had one dog that wasn't a rescue and it was a pup of a rescue.
The best was a medium small, long haired mix breed, shepherd of some sort. I picked her because she was the only dog in the kennel run at the shelter that had her tail UP but she wasn't acting mean to the other dogs.. she was just a good dog. She was white with black spots. She was Missy.
Once we came home and her right eye was hanging out and dried up. Had it removed, she didn't miss a beat.
A few years later she disappeared, we found a little blood around the back door. Months later I was out in the yard splitting some firewood and.. she came running up across the yard. She was clean and had not been out living in the wild. I don't know if someone took her and she got out or if someone nursed her then let her out but she sure was glad to be home, we were happy too. A good dog is an amazing thing, so is a good cat.
