<human>: I've got a bit of a conundrum. I'm trying to work at teaching my dog proper manners in greeting other dogs. I'm fine with working with my dog.  I do my best to only allow my dog to move forward if the leash is loose and having my dog focus on me, rinse and repeat until a calm greeting. My pup's ultimate reward is meeting other dog's.  It's other people and their dogs have 0 concept of this though and it has led to some dangerous situations. 

An example I can think of is there's a huge beautiful Newf in town. He's about 200lbs. His owners walk him on a choke collar (can't change other people's useless ideals there) which has 0 effect on him. If my dog and him see each other the Newf will drag his owner into traffic and across the street just to say hello. 

So my issue is staying consistent in my training. I can cross a street for most smaller dogs to stay consistent but with these larger dogs I have 0 consistency and give in for the other dog and its owner's safety. 

There is a secondary issue of if I never let my pup greet these other dogs due to their lack of training my pup wouldn't be socialized. I've introduced my pup to everyone and everything possible thus far. How doe it effect socialization if I stop all greetings (aside from preventing the dangerous situations as exampled above) until I get the calm manners I'm looking for?
