This is probably an odd question, but... When I play with dogs, I like to be a tad 'rough' (not total rolling-on-the-floor roughhousing, but during play I'll give a gentle tug to their ears or tail-- as long as I know that dog is OK with that kind of behavior). But one thing I tend to do when playing tug-of-war is growl. I was... a bit of an odd child, and taught myself how to growl and hiss when I was pretty young. I actually sound quite a bit like a dog when I do so, which has managed scared the crap out of my friends a couple times when they didn't realize it was me. I don't really growl at any other time except tug-of-war, but I'm concerned that I may be training them to growl. Though if the growling is only during tug-of-war, would they associate the two and understand it's only acceptable to growl during that one game? I don't want them to start growling at people trying to pick up their ball to play fetch. Or guarding their food bowl. Or in absolutely any situation other than tug-of-war.
Now, I've never had my own dog. This is just from playing with other people's dogs. I've caught myself doing it a couple times and asked the owners about it. They usually just brush it off and tell me it's fine, though their attitude seems more as if they've interpreted my question as me being afraid of a growling dog rather than me being concerned about giving them bad behaviors. I've been reading training books and doing breed research for about 2 or 3 years now in preparation for when I am ready for my own dog, and hopefully will be ready in the next year or two, but this isn't exactly something that comes up a lot in training books.
