How to tell the age of a puppy and how to tell the age of a puppy?

An examination of a dog's teeth will tell its age.

Dogs give birth to deciduous teeth ten days after birth, and after two months, they begin to gradually change from incisors, canines, and molars to permanent teeth, and the permanent teeth are replaced in 8-10 months, but it takes 1 and a half years to grow solid teeth. It doesn't matter if the puppy swallows the replaced baby teeth, because the baby teeth are softer and the dog's stomach and intestines can digest them.

To judge a dog's age with teeth, three conditions are required:

1).The bite of the teeth should be normal;

2).To feed dog feed or dog bones;

3).There must be no periodontal disease.

Stage 1 Under 2 months Only deciduous teeth (white, thin, sharp).

21-28 days 3rd mammary premolar erupts.

21-35 days Milk canines erupt.

21-42 days 4th mammary premolar erupts.

28-42 days 2nd mammary premolar erupts.

2 months All the baby teeth are in full bloom.

The second stage is 2-4 months to replace the front teeth.

3-4 months Permanent incision erupts.

Stage 3: 4-6 months Replacement of canines (white, cusps round and blunt).

4-5 months The first permanent premolar erupts.

4-6 months Permanent canine teeth erupt, and the first permanent posterior molars of the upper and lower jaws erupt.

Stage 4 6-10 months Molar replacement.

4-7 months The second permanent posterior molars erupt.

5-6 months The 3rd permanent incisor erupts.

5-7 months The permanent premolars are aligned.

6-9 months The permanent premolars are aligned.

After 9-10 months, all permanent teeth grow in alignment.

Stage 5 1-5 years old As we age, there is slight wear and tear on the teeth.

1 year old Teeth are straight, permanent teeth are long, white and shiny incisors have spikes, and incisors have no spikes.

1 1/2 years old The tip of the first incisor of the lower jaw is worn.

At 2 years of age, the cusps of the lower incisors are partially flattened, and some canines have accumulated calculus.

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

3 years old The upper incisor cusps are partially ground.

3 1/2 years old The tip of the first maxillary incisor is worn.

At the age of 4, the upper and lower incisors begin to wear and tear slightly beveled and yellow, and the calculus and dirt of the teeth can be clearly seen, and the incisors of the lower jaw are gradually worn out.

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 3rd incisor of the mandible, and the incisor grinds the surface? Rectangular in shape, with slightly worn canine teeth.

Stage 6 6-10 years old Tooth wear is significantly worse and teeth begin to weaken 6 years old The third incisor of the upper jaw is worn, the canines are blunt and rounded, the amount of dental calculus has been quite large, and the canines have begun to weaken.

At the age of 7, the teeth begin to loosen, and the first incisor of the lower jaw is worn down to the root of the tooth, and the grinding surface is oval.

At 8 years old, the abrasion of the 1st incisor of the lower jaw is tilted forward, the canine teeth are yellowed and wear the lips, and at the age of 10, the abrasion surface of the 2nd and 1st incisors of the upper jaw is oval.

Stage 7 After the age of 10, teeth begin to fall out.

After the age of 10, front teeth with alveolar abscess begin to fall out.

16 years old Tooth loss.

20 years old, canine tooth loss.

Knowing the adult size of the dog and then contrasting, if it is not more than one-sixth is three months.

Just look at the teeth:

19-28 days of age, the deciduous incisors erupt.

21-28 days old, 3rd mammary premolar erupts.

21-35 days old Milk canines erupt.

21-42 days old 4th mammary premolar erupts.

28-42 days of age, 2nd mammary premolar erupts.

At 2 months of age, all the deciduous teeth are in full bloom.

3-4 months old Replacement of the 1st and 2nd incisors and permanent incisors 4-5 months old Replacement of the 1st mammary premolar, permanent premolars 4-6 months old Replacement of canines, permanent canines and 1st permanent posterior molars of the upper and lower jaw 4-7 months of age Replacement of the 2nd posterior molars and permanent teeth.

At 5-6 months of age, the third incisor is replaced and a permanent tooth is incurred.

5-7 months of age: 2nd, 3rd, and 4th permanent premolars erupt at 6-9 months of age, and 3rd permanent posterior molars of the mandibular erupt.

9-10 months of age, all permanent teeth are replaced.

1 year old permanent teeth are long, white, shiny, and the incisors have sharp protrusions.

1 1/2 years old The tip of the first incisor of the mandible is worn.

2 1/2 years old Worn tip of the second incisor of the lower jaw.

3 and a half years old The tip of the maxillary 1st incisor is worn.

4 1/2 years old Wear on the tip of the second maxillary incisor.

At the age of 5, the tip of the 3rd incisor of the lower jaw began to wear, the 1st and 2nd incisors began to wear out, and the canines began to wear.

6 years old, the tip of the third incisor of the lower jaw begins to wear, and the canine teeth are blunt and rounded.

7 years old The first incisor of the lower jaw is worn to the base of the tooth and ground into an oval shape.

8 years old The first incisor of the lower jaw is worn and tilted forward.

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

20 years old, canine tooth loss.

Generally, if you look at its teeth, you can basically see it, and then you can see it even if you look at its bones.

It can be distinguished in this way: the first point: look at the bones, bones can be observed by age.

If a one-month-old puppy has a larger skeleton than other dogs at one month, then it is likely to be a medium-to-large dog. The second point: look at the paws, generally speaking, small dogs have smaller paws and more delicate, while large dogs have thicker and larger paws, so they can also be judged by this.

The life span of dogs is generally between 12 and 15 years old, 2 5 years old is the period of young adults of dogs, the body has fully grown up, the body structure has reached a perfect degree, and the physical strength has reached its peak, 7 or 8 years old, the dog slowly begins to age, and the reproductive ability is completely lost around the age of 10. The life span of dogs is related to breed, breeding, management and use, etc., usually the life span of hybrid dogs is greater than that of purebred dogs, small dogs are larger than large dogs, male dogs are larger than female dogs, and black dogs are greater than other colored dogs. The age of the dog is compared to that of a human, and the dog is equivalent to 1 year old.

The age of the puppy can be judged from his teeth, or from its hair, whether it is leg hair or fetal hair? And is his teeth replaced or something? Look at this dog of yours for about two or three months.

You can look at the size of the dog and the color of the coat, these are the age of the puppy can be judged, and your dog should be less than a year old.

Tooth discrimination method Ordinary dog babies will fall out of their primary teeth after birth at about 5-7 years old, and give birth to permanent teeth Only baby teeth under two months are "white and fine-pointed" and replace canine teeth in four to six months, "white round and blunt" one-year-old teeth are full Four to five years old, the upper and lower incisors begin to wear out and begin to turn a little yellow The older the dog, the more serious the tooth wear, and the word old teeth can explain all this.

If you want to tell the age of the puppy, you can generally tell it according to its size and the length of its teeth.

If you want to tell the age of the dog or the age of the puppy, the dog will mature in about a year, and you can distinguish it very well before.

If your dog is like this according to its size, it will belong to a one-year period, about two or three months.

If you want to play this, you just need to look at his age to identify it, and you can see who can help you with his incontinence.

You can see how old the dog is by looking at the dog's teeth, and there are a few that are just a few years old.

Without giving the exact age, you look at its coat color and teeth.

Generally, I look at the teeth, and the above is more detailed.

You can go to a pet hospital or a pet store and ask.

Ordinary dog babies will lose their baby teeth and give birth to permanent teeth after 5-7 months of birth.

If the baby dog's baby teeth have fallen and the permanent teeth have not been exposed or not exposed much, the upper and lower teeth of the adult dog are worn, and the upper and lower teeth of the adult dog over 4 years old are often flattened due to wear.

For 7-8-year-old dogs, the age of the dog can be determined according to the length of the dog's teeth.

The age is generally only 5-6 months;

If all the teeth are full, the age is about 8-12 months.

Before adulthood, the growth of teeth shows the age of the dog, but after adulthood, the age of the dog can be determined by the wear and tear of the teeth. Therefore, identifying the age of a dog requires a certain amount of practical and observational experience.

Identifying the age of a puppy can be identified by teeth and morphology.

How old is it, I want to get vaccinated, I'm afraid that its previous owner has vaccinated it.

The age of the identification dog is mainly determined according to the growth and wear of its teeth, as well as the appearance and color. In general, puppies have a total of 28 baby teeth. 6 upper and lower incisors, 2 upper and lower canines, and 6 upper and lower premolars.

Adult dogs have a total of 42 permanent teeth. 6 upper and lower incisors, 2 upper and lower canines, 8 upper and lower premolars, 4 upper molars, and 6 lower molars.

The parameters for determining age based on changes in teeth are as follows:

18-22 days: The dog's young teeth begin to erupt.

4 6 weeks of age: primary incisors are ingrown.

2 months of age: all the baby teeth are full, white, thin and shiny.

3 4 months of age: Replacement of the first deciduous incisors.

5 6 months of age: replacement section.

2. Third deciduous incisors and deciduous canines.

After 8 months of age: all baby teeth are lost and replaced with permanent teeth.

The permanent teeth are long, white and shiny, and the sharp processes on the incisors are not worn.

Age: The large spikes of the first incisors of the lower jaw are worn to the level of the small spikes, at which point the spikes are abrasioned.

Age: The pinnacle of the second incisor of the lower jaw is abrasion.

Age: maxillary first incisor tooth pinnacle abrasion.

Age: maxillary second incisor tooth pinnacle abrasion.

Age: The pinnacle of the third incisor of the upper jaw is slightly worn, and the wear surface of the first and second incisors of the lower jaw is rectangular.

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

Age: The first incisor of the mandible is ground to the root, and the wear surface is longitudinally oval.

Age: The first incisor of the mandible is worn and tilted forward.

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

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

In addition, according to the dynamic changes of dog hair, the age of the dog can be initially estimated: 6-month-old puppies begin to moult; 6 to 7-year-old adult dogs, white fur begins to appear around their mouths; For dogs over 10 years old, white hair begins to grow on their heads and backs, and the coat on their whole body is often lacklustre.

The age of the puppy can generally be determined by looking at the teeth:

1. Dogs erupt in deciduous teeth ten days after birth;

2. After two months, the incisors, canines, and molars will gradually change to permanent teeth;

By 10 months, the permanent teeth are replaced, but it takes 1 and a half years of age to grow solid teeth after bending;

Around the age of the upper and lower incisors, the upper and lower incisors began to wear out slightly beveled and yellow, and it was obvious that the calculus and dirt of the teeth were buried, and the Changchun incisors of the lower jaw were gradually worn;

The teeth begin to loosen, the first incisor of the lower jaw wears down to the root of the tooth, and the grinding surface is oval;

Teeth begin to fall out after the age of age.

Generally, the age of the puppy can be determined by looking at the teeth:

1. Dogs erupt in deciduous teeth ten days after birth;

2. After two months, it began to gradually change from incisors, canine teeth, and mortar teeth to permanent teeth;

By 10 months, the permanent teeth are replaced, but it takes 1 and a half years of age for the teeth to grow solid;

Around the age of age, the upper and lower incisors begin to wear and appear slightly beveled and yellow, and the dental calculus and tooth dirt can be clearly seen, and the incisors of the lower jaw are gradually worn out;

The teeth begin to loosen, the first incisor of the lower jaw wears down to the root of the tooth, and the grinding surface is oval;

Teeth begin to fall out after the age of age.

With all kinds of decorations, it is becoming more and more difficult to judge the age of a dog, but as long as you look carefully, you can still find the key parts that can judge the size. As we all know, checking a dog's teeth can tell its age. So why do teeth show a dog's age?

If you think about it, people's teeth are worn out every day because they have to eat every day, and slowly people's teeth will break out, and it is normal for people to get older and have no teeth, and the older your teeth are, the more yellow they are, and so on. Therefore, among the various parts of the dog's body, the most unconcealed old thing is the teeth, which is similar to people. All we say to judge the age of a dog, the most important thing is to look at the wear and tear of the dog's teeth.

Of course, it also takes into account its facial expressions, posture, fur, and movement status. Generally speaking, there will be the following situations: When the dog is 1 year old, all the teeth have grown; At the age of 2, some dogs have dental calculus; At the age of 3-4 years, calculus and dirt on the teeth can be clearly seen, and the front teeth of the lower jaw are gradually worn out; Around the age of 5, the tips of the teeth begin to wear; Around the age of 6, the amount of dental calculus has been quite large, and the dog's teeth have begun to weaken; At the age of 7-8 years, the teeth begin to loosen and the incisors of the lower jaw will be ground round; After the age of 10, the front teeth with alveolar abscess begin to fall out. Of course, the above phenomenon will vary depending on the breed of dog, because of the different physical health conditions and other differences, can not be generalized, the need to dog people to exert their own wisdom, after a variety of investigations, to make a normal judgment.
