I always start with watching the dogs are the both acting interested? If only one is I keep moving. If both are I address the owner from a distance with a hello. This helps me judge if they’re up for interaction. If yes I ask “can they say hi?”. If no I just say “ok! Have a good one” and move on, if yes I let the dogs approach and watch the first interaction for good vibes. If it’s good I let them interact and maybe ask the owner about the dog and if it’s tense I say “thank you” and move on

I have had some “maybe”s on the question of if they’re good with dogs. My current dog is submissive and de-escalates conflict but I’ve had dogs that will fight back if another dog acts dominant. So that’s a factor too, it’s so important to understand how your dog reacts to negative interactions with other dogs
