Feeding exists exclusively for that reason. I have three wolves in my creative-build world in my mountain home and none of them ever produce more wolves.

I didn't feed them outside of taming. I dug a deep ditch, parried two wolves into that ditch (because they won't otherwise go in) - dropped 10 boar meat and went AFK to watch FIFA WC final. At half break - both were tamed, so I dug'em out of the ditch and brough home. As soon as I crossed the gate - baby wolf appeared, lol.

So ok, I won't give them anything to eat which is even better - more nom nom for me, lol. Hopefully stuff remains under control and they won't steal meat of a cooking station when hungry :))
