He's a 1 1/2 year old Aussie/GSP mix. My understanding is that he's very friendly and playful, which their older BC does not appreciate, and it's becoming a problem. Everything she's told me about him so far matches my criteria nicely, so I have my fingers crossed We're going to the dog park to let the dogs meet and see how it goes tomorrow morning.
