At what age does a dog first begin to get its teeth?

A dog begins to develop its teeth around 21 days of age, which is approximately 3 weeks. Therefore, by the time a dog reaches 1 month old, it typically has started to see its baby teeth emerging. This is a significant milestone in a puppy's development, as teething not only aids in their ability to eat solid food but also plays a role in their exploration of the environment through chewing.

The timeline for a dog's dental development is crucial for understanding their needs during the early weeks of life. By 2 months, puppies typically have a full set of baby teeth, which will eventually be replaced by permanent ones, and knowing this can help in planning for appropriate nutrition and care during their growth.
