1 year old Teeth are straight, permanent teeth are long, white, shiny incisors have sharp protrusions, 1 and a half years old The tip of the first incisor of the lower jaw is worn.

2 and a half years old The tip of the second incisor of the lower jaw is worn.

4 1/2 years old The tip of the second maxillary incisor is worn.

5 years old There is a small wear on the tip of the third incisor of the lower jaw, the grinding surface of the first incisor is rectangular, and the canine tooth is slightly worn 5

6 years old The third incisor of the upper jaw is worn, and the canine teeth are blunt and rounded.

7 years old The first incisor of the lower jaw is worn to the root of the tooth, and the grinding surface is oval 8 years old The wear of the first incisor of the mandible is tilted anteriorly.

10 years old, the abrasive surface of the 2nd and 1st maxillary incisors of the lower jaw and maxillary 1st incisors is oval, and 16 years old The incisors are lost.

20 years old, canine tooth loss.

The meat of puppies is relatively tender and easy to bite.

The meat of an old dog is difficult to cook and cannot be bitten.

You'll find out if you taste it yourself.

It's not good-looking, because the dog is small, and it generally depends on the dog's size and hair.

Generally, it is not easy to divide, and when it comes to changing teeth, you will know, and dogs generally start to change their teeth at the age of four months.

Judging the age of the dog mainly depends on the wear and loss of the dog's teeth, and should also refer to its facial expression, posture, coat, as well as the occurrence of senile hair and age-related eye changes.

The number of deciduous teeth and permanent teeth in dogs is different, 28 deciduous teeth and 42 permanent teeth, and the last teeth that erupt are posterior molars (that is, posterior molars), which erupt at about 5-7 months of age.

Judging by the degree of wear and tear of the teeth:

The 1-year-old dog's permanent teeth are long, white and shiny, and there are sharp protrusions (also called "spikes") on the upper part of the front teeth;

The large spike of the first incisor tooth of the lower jaw of a one-and-a-half-year-old dog is worn to the level of the small spike, a phenomenon called "spike wear";

2 and a half-year-old dogs with a pinnacle of the second incisor of the lower jaw worn out;

By the age of 3 1/2 and 4 1/2 years, the peaks of the maxillary first and maxillary second incisors are worn out;

At the age of 6-7 years, the peak of the third incisor of the lower jaw is worn out, the canine teeth are obtuse and rounded, and the first incisor of the lower jaw is worn to the root of the tooth, and the wear surface is longitudinally oval;

The worn surface of the second lower and upper mandibular first incisors of a 10-year-old pet dog is longitudinally oval;

By the time the dog is about 16 years old, the front teeth begin to fall out and the canines are not aligned.

Around 2 years of age, the hair on the dog's mouth, nose, or under the chin may begin to turn gray (this is not particularly accurate due to genetics and stressors). But if you notice that your dog's whole body color is graying (chest, face, armpits, ears and nose, etc.), that's a sign that he's starting to enter old age.

When your dog gets very old, his eyes will gradually become blue, like a blue film covering them, which is caused by the aging of the lens, which does not cause serious vision loss at first.

Look at the age of the dog can look at the teeth.

Dogs under 2 months of age only have fine tip baby teeth, 2 4-month-old dogs are changing their incisors, 4 6-month-old dogs begin to change their canine teeth, 6 10-month-old dogs begin to change molars, all the dog's teeth are full at about one year old, and the cusps of the lower incisors of the dog at about two years old begin to be smoothed. The age of the dog can be determined by the tooth observation method, and if there are only thin, sharp baby teeth, the age is generally less than two months.

If you have started to have your incisors replaced, you should be 2-4 months old. Dogs that start to have their teeth replaced are about 4-6 months old, and after they have started to have their molars replaced, they are 6-10 months old. When all the teeth are full, it means that they are about a year old.

At about two years old, the dog's lower incisor teeth are partially grounded, and at about three years old, the upper and lower incisors of the dog will begin to wear and smile and turn yellow.

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, dogs eat grass not to satisfy hunger, but to clear the stomach, mainly because of the unique structure of the dog's stomach. The stomach of a dog is large, accounting for about 2 3 of the abdominal cavity, while the intestine is very short, accounting for about 1 3 of the abdominal cavity, so dogs basically use the stomach to digest food and absorb nutrients, and it is easy to digest meat food, and it is not easy to digest things with "tendons" such as leaves, grass, etc.

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 for conditions such as dog sledding in Iditarod in Alaska and other similar situations of extreme stress, high-protein foods (high meat consumption) can help prevent muscle tissue damage.

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.
