How does Pomeranian judge the age of a dog? Ordinary puppies will lose their deciduous teeth and give birth to permanent teeth 5-7 months after birth. Therefore, if a puppy's deciduous teeth have fallen out and the permanent teeth have not yet been exposed or not much is exposed, the puppy is generally only 5-6 months old. If all the fangs are fully grown: the age is about 8-12 months.

Before adulthood, the growth state of the teeth shows the increase in the age of the dog, but once it reaches adulthood, the identification of the dog's age can be determined by the wear state of the teeth. Therefore, identifying the age of a dog requires certain practice and observation experience.

Under normal circumstances, in adult dogs over 3 years old, the joints between the upper and lower front teeth of the upper jaw and lower jaw are somewhat worn. In adult dogs over 4 years old, the joints between the upper and lower front teeth often become flat due to wear. For 7-8 year old dogs, the age of the dog can be determined based on the length of the canine teeth.
