MYTH: “CALCIUM CONTRIBUTES TO EARS” Actuality: Ears are cartilaginous tissue, and cartilage does not absorb calcium. This myth is especially common among owners of dogs with erect ears. In some breeds of such dogs between the ages of 4 and 6 months, when baby teeth change, their ears slightly droop. Owners add calcium and vitamins to the puppy’s diet, which supposedly changes the situation. However, science does not confirm the effect of calcium on this process. But it is precisely known that excess calcium can badly affect the formation of puppy bones.
