How do you tell the age of a Pekingese? Observe the Pekingese’s teeth. The puppies will grow deciduous teeth more than ten days after they are born, then canine teeth, molars, and then transform into permanent teeth until the permanent teeth are complete at one year old. Young Pekingese are lively and active, and their bodies are light. Adult Pekingese are relatively stable, and their gait becomes slower in old age. Children's eyes are clear in childhood, become resolute in adulthood, and become cloudy in old age.

　1. Observe teeth

Pekingese dogs have different teeth at different stages. Generally speaking, puppies will have deciduous teeth about ten days after they are born, and then they will have incisors when they are two months old. Canine teeth, molars, transform into permanent teeth. When the Pekingese reaches ten months old, all the teeth can be replaced. To be more specific: deciduous teeth will erupt on days 19 to 28, third deciduous front teeth will erupt on days 21 to 28, and deciduous canines will erupt on days 21 to 35. Then until two months old, the dog's teeth will all grow in. Every month thereafter, the Pekingese’s deciduous teeth will be slowly replaced by permanent teeth. Until one year old, all permanent teeth will appear.

　2. Posture judgment

Pekingese dogs in their childhood are more lively and active, with a light body, able to easily cross any obstacles, and have the courage to try. They can be regarded as as light as a swallow. When Pekingese dogs reach adulthood, basically starting from the age of five, they will become relatively stable, will think a little before doing anything, and will no longer be as adventurous as they were when they were young. And I will keep them in a relatively stable state of action at this time. When the Pekingese reaches old age, it is basically ten years old. Their movements will become slower, and some Pekingese dogs may even become disinclined to run, jump, and walk. This is still very obvious upon observation.

　3. Eyes

There are no impurities in the Pekingese’s eyes when they are young. They are very clear. Those watery eyes will melt your heart in minutes. As adults, their eyes only become resolute and piercing. When Pekingese dogs enter old age, their eyes will become cloudy and even suffer from cataracts. According to data, more than 80% of elderly dogs will suffer from cataracts. Also, their eyes' reaction to stimulation will become slower at this time.
