To me that's perfectly acceptabe. Just like small dogs need to learn to accept large dogs, large dogs also need to learn to give small dogs space. Growling is communication, and as long as the other dog recriprocates - backs off - and your dog doesn't try to go farther - like snapping at the other dog as he's backing off - I think it's perfectly good communication.
