Ok so I have to throw in my two cents here.. We have three Aussies , One Shepherd and One Aussie/Border Collie mix. We adopted the Mixed Aussie/Collie. She's a real sweet heart . Lives to please and be loved ! We haven't taken her on the boat for only one reason. She was a rescue dog. So leaving home scares her to death. She was about 6 months we went took her in. If I had gotten her as a puppy she'd be a traveling dog !
I vote Mini Aussie or Mini Border Collie !
