How much of a different in size are Border Collies and Blue Heelers, and how big are they compared to adults? Dog Breed Discussions
I may be adopting a Blue Heeler or a Border Collie, or any medium sized Aussie dog. If you can think of a good small-medium or medium sized Aussie dog, that would be great, but I want to know how big Border Collies are to Heelers and how big they are compared to a normal adult.
