Thanks, definitely pup and adult would be supervised :) They'd be alright when the pup's grown though, right? And I knew what they were like with each other by then?
I used to have an Australian Terrier mix, one of the best dogs ever.
Question about female dogs since I'd be looking to get a female dog with my boy… My Lab has a female Lab friend who the new dog probably would see too, do you think terriers or Australian Shepherd females (or any other of these breeds) would do ok socialising with other females? I always worry about that.
