I do not know if this is true, but it is what my vet told me. My vet said that when one ear is down, it means that the puppy is teething on that side of it's mouth. This has proved true with Riley up to this day. He is 9 months old and has a case of double canines. The left one just recently fell out, and during the time before it fell out when it was loose, his left ear was floppy. |
