He came from a dog my "friend" came here with one day and when he went to leave the dog ran, he then told me that he had gotten the dog 2 hours before! the next day, guess what, the dog in question was....well, ready for male companionship!she was a black chow/lab mix,since she couldn't be caught, several visitors came calling and the result was 5 pups, one cat grey with long hair, two black,one with short hair one long haired.one white long hair and one BIG red, short haired pup with a big fat head,TANK
