I don’t think your situation really fit the metaphoric one because the dog kept coming over to your dogs to check them out. It was a bit of a spoiled brat, wanting everything on it’s own terms, including the right to sniff your dogs without getting sniffed back. But I do think that all the dogs needed to be under control and if Uncle thought his dog was being bothered, targeted, or whatever, it is his responsibility to protect it from that situation, including removing it if that is what he thought was needed. Nagging at your dogs certainly didn’t help in any way.
