Landlord oh oh oh !! Thank you!!

To see the wear and tear of the teeth, you need a professional veterinarian or a very professional person to see it.

The way to see the age of a dog is to rely on the wear and tear of the dog's teeth

The age of the dog is usually seen by the dog's teeth. If the dog's teeth are thin and curved, the color is not very white, and the number does not reach 42, then the dog is a young dog under eight months, and if the dog's teeth look strong and strong, the shape is not bent, and the number is 42, then the dog's age is more than eight months old adult dogs. The teeth of adult dogs will have different degrees of wear and tear due to differences in eating habits.

Young dogs are light and agile when they are active, and they are a little clumsy when they are 2 or 5 years old, but they are stable, safe and reliable. Elderly dogs over 10 years of age, with sluggish demeanor, a crooked or bent back, and slow walking. Dogs over 10 years old have a lot of white hair on their foreheads, faces and heads.

Over 13 years old, the entire head turns white (there are some dogs when they are 10-14 years old, the coat color remains the same).

Dog's diet

Dogs are omnivores, and when feeding, they need to prepare more animal protein in the feed, supplemented by vegetarian ingredients, to ensure the normal development and health of the dog. Dogs sometimes eat grass, but eat very little, and occasionally vomit out, dogs eat grass not to satisfy hunger, but to clear the stomach, mainly because the dog's gastrointestinal structure is unique. A dog's stomach is large, taking up about 2 3 of the abdominal cavity, while the intestine is very short, about 1 3 of the abdominal cavity, so dogs basically use their stomach to digest food and absorb nutrients, and it is easy to digest meat food.

Dogs are omnivores, and they can survive on foods such as vegetables and grains when life is difficult. This type of diet of typical wild carnivores comes from the stomach contents of the herbivores they catch. In addition, scientists have found that high-protein foods (high in meat) can help prevent muscle tissue damage in situations such as dog sledding races in Alaska's Editarod and other similar extreme stresses.

We can judge the age by the dog's teeth, generally around 1 year old dog teeth will grow round, the older the dog teeth will be worn out, and walk more slowly, in addition, as the dog grows older, the dog's jaw will grow a lot of gray hair, and the young dog hair is very smooth, it looks more energetic.

Generally, a normal dog only has baby teeth about two months after birth, the teeth are very white and relatively thin, and the teeth will be round when they are about 1 year old, and the teeth will begin to wear out a little yellow when they are 4 or 5 years old, and over time, its teeth will be worn out more seriously.

Generally, young dogs are very energetic, just like young people, they don't like to stay honestly, and they will walk more steadily, and their vitality has gradually decreased since they were 4 years old, and dogs over 10 years old walk more slowly, just like the elderly, some dogs will walk with their backs hunched.

As the dog gets older, the hair on the body will also change, especially the position of the jaw, the older the dog will grow more white hair, and it will lose hair, while the young dog has very smooth hair and looks more energetic.

The age of the dog is mainly determined by the growth of the teeth, the peak of the teeth and the degree of tooth wear, and the appearance and color. In order to make it easier to grasp, the tooth style of the dog is introduced as follows:

The adult canine (permanent teeth) tooth type is incisors, canines, premolars, and molars with a total of 42 teeth. There are a total of 28 incisors, canines and premolars, and 1 premolar and molars are missing. The canines are all short-crowned, maxillary.

The crown of the first and second incisors is three-peaked, the middle is the canine pinnacle, there are small pinnacles on both sides, and the rest of the incisors each have two small canine pinnacles, the canines are conical and curved, the tip is sharp, and it is a powerful force for attack and self-defense, the front day teeth are three-shaped, and the sun teeth are multi-peaked.

Age is determined based on the following criteria:

Teething begins in about 20 days.

4 6 weeks of age: Deciduous incisors are long. At nearly 2 months of age, the baby teeth are all full-lengthened, white, thin and pointed.

2 4 months of age: Replacement of the first deciduous incisor.

5 to 6 months of age: Change.

2. 3rd deciduous incisors and deciduous canines.

After 8 months of age: All permanent teeth are replaced.

l years: The permanent teeth are long, white and shiny, and the incisors have sharp protrusions.

Age: Mandibular first incisor peaks are worn to level with small pinnacles, a phenomenon known as pinnacle abrasion.

Age: Mandibular second incisor tooth pinnacle abrasion.

Age: The pinnacle of the maxillary first incisor is abrasion.

Age: The pinnacle of the maxillary second incisor tooth is abrasion.

5 years old: The pinnacle of the third incisor of the lower jaw is slightly worn, and the mandibular is first.

The wear surface of the first and second incisors is rectangular.

6 years old: The pinnacle of the third incisor of the lower jaw is worn out, and the canines are obtuse and rounded.

7 years old: The first incisor of the lower jaw is worn to the root of the tooth, and the wear surface is longitudinally oval.

8 years old: The first incisor of the mandible is worn and tilted forward.

10 years old: The wear surface of the second and maxillary first incisors is longitudinally oval.

16 years old: Loss of front teeth, incomplete canines.

A dog's teeth are the best way to judge a dog's growth rate. The dog begins to replace the baby teeth from 105 days, and the old teeth from the front teeth of the front teeth will be slowly replaced. I finish replacing it in around 205 days.

Replaced teeth will generally look hollow. Therefore, the dog that is in the tooth replacement period must not be more than one year old, and the teeth of dogs over two years old are particularly clean and very powerful. If the dog begins to lose teeth, at least the dog will be 7 years old, and the first to fall out is usually the front teeth.

And some elderly dogs will continue to lose their teeth one after another. Therefore, in many cases, according to the total number of dog's teeth, you can also roughly calculate the approximate age of the dog.
