This process starts at the front of the mouth with the small teeth called incisors, and then works its way back, generally in a symmetrical fashion. The puppy’s mouth may bleed slightly (or his or her breath may sometimes smell like blood) as the baby teeth fall out. The deciduous teeth are generally gone by five months, and the permanent teeth generally are fully erupted by eight to 12 months of age. 8 months to 24 months old: Most dogs have reached their full height by eight to 12 months of age (although some giant breeds continue to grow for up to two years). They are adolescents — not quite puppies, but not quite mature dogs.
