Our Cattle Dog is one of those high energy breeds and she snowbirds with us in a 30 foot Class A, along with an Australian Shepherd and a lab cross, oh, and don't forget the cat!! DH and I are just along to drive the rig. Molly, cattle dog, has a tennis ball and we have a chuck-it. We can always find a place to run her because if we didn't, she couldn't live with herself.
We knew it going in but love the breed so much. She is our second one.
I think this family can make it work. I hope so, anyway because it will be so good for the kids to learn to go with the flow. Animals are a good part of that learning.
