Awwww

what a cutie pie!!!! Sooo SWEET!!!
Have you seen if anyone was missing him? I bet he hasn't been "lost" very long...he still looks good!
I have never had a problem with introducing animals to each other.....we have had the rescues brought in and course, I always make sure they are clean and clear of any pests, diseases, etc before allowing them in the house or around Mojo.
The first one we got was Sophie.....she went straight to the vet, was spayed and tested for everything, etc. She had been abused (severely) and was very submissive....her and Mojo got along sooo great! Still do.
Luke was next.......he was huge 100lbs, still intact and kept in a cage his first two years of life. We brought him out here to run free. He was very protective and didn't like Mojo at first. He went to get nuetered and checked, etc....and now, he is the big baby of the bunch...wouldn't hurt a fly and loves all the dogs.
Rusty was after Luke....he was checked out, but not neutered yet (as he was our neighbors and we just didn't know what to think of that situation). Anyway, we are still working with him on commands, etc. BUT he is a good dog. He has spurts of growling at the other dogs, etc. But he is quickly reminded who is in charge......ie...NOT him!
Lily came next and it was as if she had always been here. I mean, it was like she had acutally spent her first two years of life in this house with all of us and the dogs.
So....with us...the introductions have all been easy. I think the key is to always be there....we were lucky enough to be an "at home" family, so we were always with the dogs.
Good luck! What a cute little guy he is!!!
