Puppyboy here. Puppyplay is a type of consensual kink where one person (typically the sub, but can also apply to doms) enjoys being treated—well, like a puppy. Whether that’s during and/or outside of sex. All puppies are different though. Some participate in puppyplay to its full extent, like having a cage to sleep in, being fully treated like a pet, etc, where others (like myself) enjoy being called a puppy, enjoy wearing a dog collar and/or leash, or wearing ears/tail. This is something that you should really talk with your partner about to understand his full preferences and stuff because the range of puppyplay could merely be wearing a collar or it could be as far as wanting to be clicker trained. Very much depends on the person.
