Border Aussie Terrollie

Australian Terrier / Border Collie Mixed Breed Dogs

Information and Pictures

A medium-sized, longhaired, black, tan and white Australian Terrier/Border Collie mix breed dog is standing on a wooden deck in front of a door. Its mouth is open and it looks like it is smiling.

Sparky was an Australian Terrier / Border Collie mix. He lived to be 16 ½ years old.


The Border Aussie Terrollie is not a purebred dog. It is a cross between the Australian Terrier and the Border Collie. The best way to determine the temperament of a mixed breed is to look up all breeds in the cross and know you can get any combination of any of the characteristics found in either breed. Not all of these designer hybrid dogs being bred are 50% purebred to 50% purebred. It is very common for breeders to breed multi-generation crosses.
