When do Shelties ears stand up?

Sheltie puppies’ ears typically start to stand up between three to five months of age. Some puppies’ ears might take a bit longer to stand fully erect, but by the time they’re fully grown, their ears should be upright. If you notice that a Sheltie’s ears aren’t standing up by six months or so, it’s a good idea to consult with a veterinarian to rule out any underlying issues.
