If there was one thing Bruce had learned about being the Hulk was that the more exercise he got the better things were especially as the more tired his body and by extension brain the less chance he had of big green making an appearance. He didn't want to surround himself with people so he opted for Central Park as it was big enough with a lot of large open spaces so he could stay out of people's way and would also allow the Hulk a lot of room to move if he did happen to manifest.
He had headphones on with music playing so he didn't hear the voice instructing the dog to go get its treat and he didn't know there was a dog until one was right in his way eagerly and happily lapping up something off the ground.
Bruce's hands went to his headphones to pull them off his ears and he immediately set himself into a crouch as he gave the young dog all the attention it wanted and more. He unlike everybody else didn't see the dog for the dangerous dog that others saw but then he was Bruce and he knew a little something about having a monster inside and having the whole world judge you for it without knowing you.
"Aren't you gorgeous?" he said with a warm smile as the puppy reacted well to hands on ears and there was soon a tongue happily lapping at and taking full advantage of tasting skin. And then its owner was there and she spoke, immediately recognition dawned on Bruce and he looked up to see sure enough Val.
His lips pulled into an easy smile complete with teeth, "Hey."
