The tag alias #52407 pup_play -> puppyplay has been approved.

Reason: Both refer to the same practice. pony_play is already aliased to ponyplay, as is pet_play to petplay, so this would continue the theme.

EDIT: The tag alias pup_play -> puppyplay (forum #313884) has been approved by @Rainbow_Dash.

Alias sounds good to me.
(puppy_play already aliases to puppyplay. alias #6019 / petplay topic #3667 )
