So let’s start things off on a personal note…On his “famous” runs Rocky had a doggy with him…remember him? It turns out that there was a good reason why Rocky got along so well with the dog. The dog was Sylvester’s poocher in real life. It made sense, if Stallone wanted the Rocky character to have a dog, for the actor to have had a relationship with the animal before filming started. What is the point of hiring a stunt dog when you can bring in part of the family, right? Of, course, Sylvester was known for bringing in the family!
