That's not odd of you at all! I would say they might flop back down when he begins to teeth more. Ears are a tricky subject, as puppies they can be down one day and up the next.. Then down again!

my breeder said she had a lady buy a pup from her and the lady only wanted her to have floppy ears like her other yorkie. So she broke the cartilage in the pups ears so it would stay that way

yikes! Lol but the breeder said the cartilage can get messed up when puppies play and cause the ears to be permentaly flopped. Anyway.. I'm sure either Way your babies ears turn out they will be adorable!!
