I actually have a mixed-breed of the two! Such great dogs. For me, what I wish I had known before getting him was their sensitivity. How they need to stay alert and control their environment (as per their initial job and function), making them sensitive to noise and stress more than other breeds. Of course, I've many chill BC or AS but mine and some others go up to a point when they get stressed so bad they need medication or some oils to stop being overwhelmed. Also, yeah, smart, but smart also means they know perfectly how to get what they want or go open the drawers to steal some food! Lol the predation instinct/herding instinct is so strong in some of them...mine has never seen a sheep but has been rounding us, and unfortunately joggers and bikes. This is a serious thing I see with many of them (or even cars for some mini Australian Shepherds)...mine just got better at letting them pass by now that he is 3,5yo...but he often just runs after them, barks and circles around them until they stop...which is natural for them but I suppose scary for people. A real problem for me, so I can't let him off the leach that much...Anyway, great dog and great video ^^
