How to determine the age of the dog? How do people see a pet dog when they want to see how old the dog is? Below I share with you a complete list of ways to determine the age of a dog.

A complete list of ways to determine a dog’s age:

Determining the age of a dog relies on the wear and tear and shedding of the dog’s teeth, as well as reference to its facial expression, body posture, coat condition, and the presence or absence of geriatric hair growth and geriatric eye changes.

Wear and tear and loss of teeth. Ten days after the birth of the dog that is born milk teeth, two months after the beginning of the incisors, canines, molars gradually replaced by permanent teeth, 8 to 10 months permanent teeth for all, but need to be 1 ½ years old after the teeth to grow solid. It doesn’t matter if the puppy swallows and eats the replaced milk teeth because they are softer and the dog’s stomach and intestines can digest them. Rely on the teeth to estimate the age of the dog table.

The condition is related to age, the older the dog, the more severe the wear. However, it also has a lot to do with the nature of the animal’s food, e.g. a dog that eats a lot of soft food and chews on bones will not have the same tooth wear, so it should only be used as a reference.

6 years The tip of the mandibular 3rd incisor is beginning to wear down and the canines are bluntly rounded

7 years old Mandibular 1st incisor worn down to the root of the tooth, worn to an oval shape

8 years old Mandibular 1st incisor is worn and tilted anteriorly

10 years The grinding surfaces of the mandibular 2nd and maxillary 1st incisors are oval in shape

16 years old. Loss of cut teeth.

20 years old Canine tooth loss

The age of a dog can usually be determined by a combination of its appearance and the growth of its teeth, the degree of wear and tear, external color changes and the degree of shedding. Older dogs have rough coat, no luster, light hair color (receding hair), white hair on the lower jaw, two eyes without light, slow action young dogs have smooth coat, glossy, two eyes, energetic, flexible action, but the appearance of identification can not determine the exact age of the dog, it must be based on the dental situation to determine. Of course, the degree of wear and tear of the dog’s teeth and feed, feeding management also has a certain relationship.

facial expression

Dogs aged around 1 year old have an active expression, with a glowing, animated gaze.Dogs aged 2-4 years old are affectionate and approachable, with a glowing, enthusiastic spirit. Older dogs, greater than 7 years old, are sluggish, slow to respond to stimuli, unwilling to move much, and have dull eyes.

physique

Young dogs are light and agile when they are active, while 2-5 year olds are a bit clumsy, but steady, safe and reliable. 10+ year olds are slow to walk, with a hunchbacked or flexed spine.

Occurrence of hair in old age

Refers to the appearance of gray hairs (i.e., the original non-gray hairs of the dog becomes gray hairs), first occurs in the lip area, the jaw area. 4-5 years old dogs began to see a few white hairs, 5-6 years old when the number of markedly increased, and later diffuse to the back, around the nose, eyelids, eyebrows, etc., and then further extended to the forehead and the external auditory canal within the growth of white hairs, and even the entire Even the entire head hair becomes white. Dogs over 1 0 years of age have numerous white hairs on the forehead, face and front of the head. Over 13 years of age the entire head turns white (there are individual dogs that remain unchanged in hair color at 10-14 years of age). A change in coat color should not be used as an aid to age determination in dogs with white, yellowish-white, or chestnut-colored hair with white spots.

eyesight (dialect)

The eyes of young dogs are alert and bright, cataracts appear in the eyes of dogs over 7 years of age, cataracts occur more often in dogs over 8 years of age, most dogs between 9 and 10 years of age have cataracts, and in dogs over 10 years of age, almost all of them have cataracts. Early cataract crystals have a blue-green ring. Typically a central or central peripheral cataract, the crystal is cloudy gray or grayish white, and there is a clear green refractive reflection. Individual dogs 1-1.5 years of age may also have cataracts.
