Your dog's teeth need to be controlled since the first days of life. Especially in small sizeyou have to make sure that the definite teeth don't come out before the milk teeth have fallen out (this usually takes place between the first 4 and 6 months).

If you don't do that, you might run the risk of the dog having deformations in his mouth later on, and these are much harder to correct then.
