The yelp definitely attracts Ryoji's attention, and he wasn't about to leave a poor hurt puppy all alone. He quickly locates the source of the ruckus, removing the paper bag and grinning down at the dog.

"Hey little buddy! Are you lost? Don't worry, we'll get you home."

After holding out his hand to let the Pomeranian sniff it, he gently picks up the dog and holds him in his arms. It must be someone's dog... it has a collar that looks almost like the visitor bracelets.
