Thanks y'all! I hadn't even thought about a mini mule. Sounds fun.
I would absolutely LOVE to adopt from a shelter.
I think Rocky is definitely like a pitbull too in his desire to play and rough house. I would definitely have to find a tough mini that wouldn't break easily. He needs something that can take the licking and keep on ticking. LOL Not that he's a horrid little beast. he's just a a young boy who's still feeling his oats.
Connie P, I'm located in Alabama. I don't know of many shelters in my area that are looking for homes for minis. I've started looking online, but I still have much searching to do. I'll definitely pm ya, maybe you might know of somebody near me that has a mini horse/donkey/mule that would make a good match for Rocky that would like a home that they'd be well cared for.
