I believe you're right, Magill. If you listen to the lyrics, it's obviously not about a dog. Just the title came from the dog. I heard Paul explain in an interview not too long ago that there was a lot of nonsense lyrics in the song, that didn't mean a thing. Like "lady suffragette" and stuff like that. He was just making up words to rhyme. I think it's a nonsense song through and through. Fine by me...the song ROCKS!!
