What are the reasons for double teeth in dogs?

Double teeth in dogs usually occur during the teething period, mainly due to inadequate calcium supplementation or lack of tooth grinding during the teething process. In addition, severe double teeth may affect a dog's normal life, and even impact its lifespan. Therefore, when a dog has double teeth, it is recommended that the owner take the dog to a pet hospital for diagnosis in a timely manner to determine whether the double teeth need to be extracted. This will ensure that the new teeth can grow normally and the overall aesthetics of the teeth are not affected in the later stage.

1. Inadequate calcium supplementation

Normally, dogs begin to teethe at the age of 3-7 months. If calcium is not supplemented in a timely manner during the teething period, calcium deficiency in the dog will cause the deciduous teeth to not fall out properly, resulting in double teeth. Therefore, it is essential to supplement calcium for dogs during the teething period. You can feed the dog high-calcium dog food or give it pet calcium supplements to ensure proper calcium intake, which promotes better tooth loss and faster growth of new teeth.

1. Lack of tooth grinding

Due to the fact that modern dogs mainly eat complete dog food, they rarely chew bones to grind their teeth. If the teeth are not adequately ground during the teething period, the aging teeth will fall out slowly, while the newly replaced teeth have already grown, resulting in double teeth. Therefore, during the teething period, owners can prepare tooth grinding toys, chew toys, etc. for their dogs to increase tooth pressure, so that their teeth can fall out more quickly.

1. Genetic problems

Some dogs are born with double teeth because their parents may have had double teeth, and the genetic mutation may be passed on to the next generation. Such oral problems are more likely to occur in their offspring.
