when do puppies molars come in
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 5 or 6 weeks of age.
