Dog breed guide
Collie
A friendly, happy and active companion that the standard calls good with children and other dogs. The coat is very dense with a soft undercoat, and Dogs NSW says a good brush once or twice a week keeps the pet Collie tidy. It needs a backyard and a regular walk rather than lots of exercise.
