The dog used in the movie was a mix, but was chosen because it had the markings of a Border Terrier. "Borders" play a big role in all of this PLUS the GHWB is associated with 2 border states: Texas and Maine (Kennebunkport).

I found this:

"Border Terrier

In 1960, animal trainer Frank Inn found the dog at the Burbank Animal Shelter as a puppy. A fluffy black-and-tan mixed breed dog, he was marked like a Border Terrier, and Inn believed him to be a mix of Miniature Poodle, Cocker Spaniel, and Schnauzer."
