Don't know if you guys can see that picture but I need help on the breed of the big dog in the picture?! As a puppy we were told she was a full jack russel but clearly not as she grew to the size of a lab! Any ideas?

Possibly a bit of lurcher in there?

I'd say that she has a bit of collie in her and some kinds of terriers. She probably also has some whippet in her.
