"This is my lovable but disastrous puppy. Her mother's owner told us she is a German Shepherd / Border Collie. Fortunately she shows all the signs of a German Shepherd Dog! This is Hailey-Bean at 4 months old pleading her case after eating my favorite cookbook as an appetizer."
The Border Shepherd is not a purebred dog. It is a cross between the Border Collie and the German Shepherd. 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.
"This is Harley. He is a German Shepherd, Border Collie mix at 5 years old. He is an all-out friendly dog. He loves people of all ages. He is even great with kids! You can take him anywhere and people he has never met can come up and pet him. He won’t bite or growl. He will only kiss! He loves to give kisses! He will just cover you in kisses! Although he isn't the best guard dog he is a great companion dog!"
