As you might recall, we have fully embraced the plan to adopt a second dog. We do have small children along with our exuberant collie and a mellow, tolerant cat. After the collie/hound mix named Petey we'd been interested in adopting found himself a new home in Chicago, we've been watching Petfinder with renewed passion.

Please let me know your thoughts on this young male -- he's an ACD/blue heeler/mountain cur mix:



He's beautiful, but I'm thinking that his mix isn't the most compatible with my family/pets/no fenced yard. Am I right, or is this boy worth meeting? Might he be gentle/learn to stay in our yard? The rescue described him as being happy, loveable, likes other dogs, likes his crate, etc. Though I will absolutely ask the rescue whether they think this dog is okay with cats and kids, I'd like to know if anyone has experience with a mix like this.

Thanks for any insight!
