| One of the biggest challenges in raising a puppy is dealing with all of the chewing they do. It can be a bit less frustrating if you consider that for almost the first year of his life, your puppy is dealing with some big changes going on in his mouth. |
Dogs have two sets of teeth: 28 deciduous (baby) teeth, which will eventually be replaced by 42 permanent (adult) teeth. When a puppy is two or three weeks old, the deciduous teeth begin to erupt through the gums, starting with the incisors, followed by the canine teeth, and finally the premolars. All of the deciduous teeth should be in place by about eight weeks of age. These first teeth are small, and painfully sharp, as owners of young puppies know. This is part of the reason most mother dogs begin to wean their pups at five or six weeks of age.
Losing Their Baby Teeth
By eight to twelve weeks of age, the roots of the deciduous teeth are starting to resorb and the teeth begin to loosen and fall out. This makes room for the permanent teeth to erupt normally. As with the deciduous teeth, the permanent incisors are the first to come in, followed by the canine teeth, and the premolars. The last teeth to erupt in the adult set are the molars. Puppies do not have molars, which is why there are fewer deciduous teeth. In most breeds of dogs, all of the permanent teeth should be present by about eight months of age.
