Years ago I had a papillon named Pepe. I took Pepe to training classes to learn to socialise with other dogs , this he did except for one dog an enormose wolf hound. If one of them was late for class, the instructor had to stop the class until they had said hello. The wolfhound lay down while Pepe walked all round and were so excited to see each other. At playtime the same happened. My Pepe was smaller than the wolfhounds head. Opposites attract.
