My uncle was a dear man, he'd always tell me, when I went to the farm for holidays as a young child, that he had a cow called Betty, after me of course. LOL . Sucked in I suppose. I think it was always just the quiet one he could let me sit on while it was being milked. LOL.
Seems it was a popular dog's name(even if unpopular with me). I put all the registrations for Australian Cattle Dogs in order for the library run by our Canine Council here and it's amazing how many Blue Bettys there were way back then, with different prefixes of course.
(Named after a dog??? No, but that
would have been acceptable. )
