Methods to prevent double rows of teeth in dogs:

1. Feed the dog dry food when it is two months old and avoid eating it. Eat soft food, and eat less animal liver and meat.

2. During the tooth replacement period, you must pay attention to giving your dog more calcium. Calcium can effectively promote the growth and health of teeth.

3. Help the dog grind its teeth during the teeth replacement period. You can buy some teething toys for it, and you can also use chewing gum and ropes to do pulling activities with the dog to help it move its deciduous teeth so that the deciduous teeth can fall out easily.

Dangers of double rows of teeth in dogs:

1. It affects the normal development of permanent teeth, causing them to grow slowly and unevenly, causing mouth deformities.

2. The double row of teeth creates many gaps between teeth, making it difficult to clean food residues and easily leading to a series of oral diseases.

3. Due to being squeezed, the stability of the permanent teeth is poor, and the resulting oral diseases will cause the permanent teeth to fall out prematurely, affecting the dog's health and quality of life.
