How to determine the age of the dog

Teeth: normal teeth bite, no periodontal disease and feeding dog food or dog bones. Physical: Young dogs are active and active, while a 5 year old dog has entered middle age and will not be able to do too dangerous movements, and a 10 year old dog has begun to enter old age and will become relatively slow in action. Hair: In general, the hair around the dog’s mouth will be the first to turn white when it is 5 years old, and then slowly want to extend the entire face and back. If 70% of the dog’s head hair has turned white, it means that the dog is over 10 years old, and if the head is all white, it means that the dog is almost 13 years old or older. Changes in the eyes: The dog’s eyes become cloudy as they age, as the clarity and transparency of the crystal body decreases. And older dogs will commonly have mild cataracts or glaucoma. Therefore, the approximate age can be determined from the dog’s eye disease as well.
