I am a little wary of akitas because they are known for same-sex aggression (i.e. it's not recommended to keep two akitas of same gender!)...
but this akita sounds friendly?
He probably walked behind Rex to have a butt sniff - not to attack?
When we meet other dogs on walks, I just give my dog a long, loose leash and let them greet naturally (they will pull up alongside eachother, sniff noses, then if all is good, they'll arc around eachother to do a butt sniff...I don't let butt sniffing go on too long, because then leashes tend to get tangled and dogs get tense). If a dog is lunging, barking, or growling, then we angle our walk so there's a lot of distance and we don't meet. (The other owner is usually doing the same thing - you can tell by their body language and the look on their face if they have a friendly dog or not!)
My dog was once grabbed by the throat, by my friend's golden retriever. We pulled them apart in a second, but for months afterwards, he would sometimes growl at the sight of any golden retriever. His fur would stand up if we passed this particular dog (we of course did not try to have them meet anymore). It did wear off though! He seems to have forgotten now. Took several months in our case.
Well, that's our experience!
Oh, and this other owner should NOT be allowing his dog to drag him over!! What's up with that! Akitas get big, over 100 lbs, so this is a setup for disaster in the future.
