I think probably you should do something more, but what is the question. I've never had one that was like that. The only growl I get out of mine is when I kiss her on top of her nose when she is playing with her ball, but it is just a soft, playful growl. I do it on purpose and she'll nearly always growl, but it is so soft that you can hardly hear it. Muffin, as a puppy, growled a little while playing, but never, ever after she grew up. So, I'm thinking that you do need to nip it in the bud. It would take a bit of research to find out just how to do that.
