I think the answer is my MIL and many, many other people. It is the most popular dog’s name in the U.S.
In the case of my MIL, her Max was a chocolate standard poodle (one of the full sized ones). Max was the most flamboyant and effeminate animal of any species I have ever seen. He trotted and ballet danced rather than walked. If anyone called to him especially from another room, you could literally hear him getting himself together, prance into the room, gently set down in front of you, stare you deep in the eyes in a mournfull but loving way, and then present a limp wrist for you to kiss. He was hit by a car when he was a puppy and his jaw got permanently misaligned so his pursed lips as he looked into your eyes looked even more provocative and awkward.
He died a virgin despite not being neutered the first eight years of his life. Neutering was for health reason rather than any realistic threat of hooking up with a female. Max would sometimes take bed rest from the stress of his existence by climbing into my MIL’s place on their elegant bed and laying there depressed for days at a time (when he wasn’t kicked out). He was present at many large parties including my wedding and people would whisper: “What is wrong with that dog? OMG, What is wrong with that dog?” as they watched him go about his usual routine.
I doubt the question was about him but I think the flaming poodle from hell I knew is worthy of mention as well.
