Border Collie, Smartest dogs I have ever owned. Never had any real training and they will keep kids from getting in the pool unless I say it is OK. Keep the gardener from getting in the back yard until I said it was OK then never bothered him again. There is a path around our property from the 2 of them policing the property. But once we introduce someone to them as OK they want nothing but to get some attention from them. Great dogs but they shed ALOT. we had to get a hair trap for the pool filter to keep them from clogging it up. They love to swim and shed at the same time. Neither is a pure bred. Given to us from a breeder who had a couple fence jumpers.
