Long time no post Mike's old dog Cotton was a McNabb and was awesome. The family we got him from used to live on the McNabb ranch and that is where they got their dogs. They were less 'busy' than alot of Border collies but the working ability was the same. The ones I see on FB don't look the dogs we got our from. More spindly and all ears. Cotton was a very strong dog, could stop anything, just enough eye, and only bit when he needed to.
