Many pet owners have heard that other people’s dogs began to change their teeth when they were two or three months old. My dog is completely incompatible, and I feel extremely anxious, but in fact, every dog is unique, and their physiques are different, so it is normal for the timing of tooth replacement to be slightly different, and you don’t have to worry about it.
Normally, most dogs should start to change their teeth from two to three months after birth. If the process of tooth replacement is relatively smooth, it is usually completed in seven to eight months. However, due to individual differences, some dogs may not begin to change their teeth until they are four or five months old, and in the longest cases, it even lasts until the age of two. Therefore, if the dog starts to change teeth a little slower than others, the pet owner does not need to worry too much, as long as the dog’s baby teeth can fall off normally, and the new teeth are slowly growing.
The speed of the dog’s teeth replacement may also be affected by the following factors:
- Nutritional status
Dogs with better nutritional status develop faster, so they may change teeth earlier and faster. Therefore, pet owners should pay attention to supplementing the dog with rich nutrition during the growth and development stage and appropriately increase the types of food to be fed so that the dog’s nutrition is balanced and comprehensive.
- Bite Habits
During the period when the dog is changing teeth, pet owners need to use molar sticks, chewing gums, teeth molar toys, etc. The old teeth did not fall out normally, but the new teeth have grown in, so it is more likely to have double rows of teeth, tooth deformities, and other phenomena.
- Influence of minerals and vitamins
During the period of tooth replacement, dogs should also pay attention to appropriate supplementation of minerals and vitamins, especially calcium, phosphorus, and vitamin D. Mineral deficiencies can easily lead to slow growth of new teeth in dogs, as well as double rows of teeth.
