How many months does it take for a native dog to erect its ears?

Generally, when a native dog is three months old, its ears will stand up. When the dog’s ears are erect, the dog should be given nutritional supplements. You can feed your dog food with high calcium content, or you can give your dog pet calcium powder. In addition to calcium supplementation, it is also necessary to promote calcium absorption. You can take your dog to bask in the sun more, as ultraviolet rays can help your dog absorb calcium.
