Content: 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. Like adolescents, dogs in this age group go through puberty (if they aren’t neutered or spayed). And like adolescents, they are generally clumsy and awkward and they may have skin problems (puppy mange often strikes around this time, or sometimes a bit earlier). 2 to 3 years old: Most dogs’ physical development is complete by two years of age. Alas, it often is not long after this that time to begin to take its toll.
