I'm afraid I didn't explain that very well. If you ever watch dogs off leash, they will always choose a greeting they are comfortable with. For instance, Nellie is comfortable with another dog approaching and circling her and perhaps a butt sniff. Never approach her muzzle-she doesn't like it. Murphy is a muzzle greeter, he's okay with that. Tucker does everything and anything. He's still got a puppy brain and he's figuring out what works, I suppose, with most dogs. He's leaning toward the butt greeting. :clown: I think it's great that you're working with Jordan and helping other dogs learn to socialize, as well. And to top it off, you are in a controlled situation which is often ideal for socializing.
I can't give you a timeframe that's polite. I can tell you when someone asks if their dog can meet your dog, you can tell them... sure, if you don't mind, Jordan is a butt greeter. Does anyone have a better word for that, lol? Some sniffing and you're on your way. I wouldn't worry about being rude, I'd worry more about making every greeting a positive one for Jordan AND the other dog. Some dogs consider a muzzle greeting rude and it sounds as if Jordan isn't fond of it. I can tell you, too, there are many dog owners that think their dog is friendly and it turns out, (for whatever reason) the two dogs dislike each other upon greeting. Are you asking what cues to look for as far as body language goes? Keep in mind, you not only have to watch Jordan, but the other dogs, too.
I use different commands for different things. For my dogs,
leave it means we aren't going to go near it or touch it-ever (this works for everything but a body of water :shrug
. When I say
look or the dogs name, that means all eyes on me. Some people use watch me, here, choose a word that
only means look at you. This takes their focus off whatever they are looking at and puts it on you.
You said Jordan will sometimes get in a down position. Sometimes a down is a submissive posture to other dogs. When that happens, is it an invitation for the dogs to move closer to his muzzle?
Here is a link to a Word document that illustrates some different postures and what they mean-it's very basic. This site no longer exists, but you can open it and read it and you can save it to your computer, as well.

Really, the bottom line is that you are controlling the situation, if you want to have positive greetings between Jordan and other dogs, you have to keep them positive. They could get lengthier as time goes on and Jordan knows you've got his back.
