I want to do some research on other herding breeds. My personal doggy experiance has pretty much only been with Shelties and Border Collies. Those are all I've ever owned.Though I love both breeds very much I am interested in venturing off from my breeds when it comes to my next dog. I want an active, fun companion that is going to beable to keep up with me and my two border collies. High engergy dogs ar what Im all about. I want something that is going to love going out running, hiking, non-competative backyard agility, and maybe even do herding trials with. I am forsure considering adopting and breeds aren't all together THAT important. If I find the perfect dog then I find the perfect dog but for now I want to do some doggy research to keep me content until the time comes when I am ready to get another companion. Non herding breeds are welcome too. I was also kind of interested in terriers. I'd love to hear everyone's opinion on the breeds they are suggesting. Both the positives and the negatives.
