The Border Collie is a purebred dog with full-erected ears

The Border Collie is a dog breed with erect ears, so it is a normal purebred dog with fully-erected ears, but there are also cases where the ears are half-erected or 3/ 4. When the Border Collie is 4 months old, the Border Collie will have erect ears. If the ears are not erect, the owner can choose to help the Border Collie, feed foods high in calcium, or directly supplement calcium. Calcium powder and calcium tablets are good choices. You can also choose to use an ear erecting device to assist the Border Collie in erecting its ears, so the purebred Border Collie’s ears are fully erect.
