Curious as to why my last post was not approved.
Some Korean people just don't like dogs and some dislike them so much that if given a chance will harm any stray or unattended dogs. People may move away from you. Exsusw they do not like dogs or have an allergy or just outright fear (possibly from a bad experience).
While I have 2 dogs myself I don't see any need to try and force them upon people who want nothing to do with them and indicate such by moving away or crossing to avoid being in close proximity to them.
So step back and rethink why you want to say this phrase to strangers when you know nothing about why they are not inclined to be near your pups.
Let people do as they wish in regards to interacting or not, with you and your dogs, and not try to impose your wish for your dogs to be loved and appreciated by everyone. It's a tad selfish.
