It is absolutely amazing how similar these 2 Border Collies are in their nature and personalities and even in their movement. Well, they are brother and sister but from different litters. It is really interesting. I just wonder how much of the similarity is in the genes and how much comes from the sister (1 year old) copying the brother.
Look at this action shot for instance: both hind legs of both dogs are in the air in more or less the same position. The front legs also are in similar positions. And this is only one of the many pics I have of them showing such similarities. Not even to mention my daily observations of them. It is like one dog having a permanent mirror next to him.
