Georgia sounds lovely! Mika (my labx) doesn't do well with large black dogs, hyper dogs, huskies or akita's if they all bug her when we are at the doggie park. I usually can whistle/call her away before she snaps at them, but often she'll just give them one snap and it's all over, she walks away. When she's on a leash she'll really have a go at any other dog. My other dog gets on fine with any other dog, but also goes nuts thru the fence or while on a leash. Crazy animals!
