Here is the full story of sweet JIMMY http://thearra.com/2017/04/06/homeless-dog-who-followed-a-human-he-didnt-know-into-her-home-is-in-need-of-a-home-or-rescue/ Who knows what his mix is really - he is well and truly a MUTT ( the best :) This is a really wonderful dog - full of personally and love. If you have a tennis ball he will be your friend for life ! Jimmy is about 45 lbs and 6-8 yrs old but you would never know it If you watch his video, I think he's more of a Belgian malinois mix. Very athletic, highly intelligent, sensitive. He gets a long with dogs, people and children.
