How can you tell how long a small pet dog can generally live to age?

In general, the distribution of permanent teeth in adult dogs: 6 upper and lower incisors, 2 upper and lower incisors, 8 upper and lower premolars, 4 molars and 6 lower jaws, a total of 42. Distribution of the number of deciduous teeth in puppies:

There are 6 upper and lower incisors, 2 upper and lower canines, and 6 upper and lower premolars, for a total of 28. The age of the adult dog is most obvious in the growth, wear, sharpness and bluntness of the teeth, and the age of the puppy can be judged from the number of canine teeth, strength, new and old, brightness, etc. The age of the dog is roughly determined according to the following criteria:

After about 20 days, the teeth gradually erupted unevenly.

At 30-40 days, the deciduous incisors grow together.

At 2 months, all the baby teeth are full, thin and white.

2-4 months, replace the first deciduous incisor.

5-6 months, replace the first.

2. The third lactoinor and all the deciduous canines.

After 8 months, all teeth are replaced with permanent teeth.

At 1 year old, the permanent teeth are long, smooth and firm, and there are sharp protrusions in the upper part of the incisors.

years, the pinnacle of the first incisor of the lower jaw is worn out.

years, the pinnacle of the second incisor of the mandible is abrasive.

years, maxillary first incisor pinnacle abrasion.

years, maxillary second incisor tooth pinnacle abrasion.

At 5 years of age, the pinnacle of the third incisor of the mandible is slightly worn, and the mandibular is at the same time.

1. The second incisor grinding is rectangular.

At the age of 6, the pinnacle of the third incisor of the lower jaw is worn out, and the canines are obtuse and rounded.

At the age of 7, the first incisor of the mandible is worn to the root of the tooth, and the wear surface is longitudinally oval.

At the age of 8, the first incisor of the lower jaw is worn and tilted anteriorly.

At 10 years of age, the worn surfaces of the second and maxillary first incisors are longitudinally oval.

16 years old, incisors are missing, canines are insufficiency.

20 years old, canine tooth loss.

If a small pet dog is well raised, then it is no problem to live for about 15 years.

I grew up watching my neighbors have dogs. 20 years should be fine!

The average lifespan of small dogs is 12 to 15 years, and there are some dogs that live up to 20 years, with the longest life record being 34 years.

2 to 5 years old is the prime of life for dogs, after the age of 7 they begin to age, and they lose their reproductive ability around the age of 10. The lifespan of dogs is closely related to the conditions of feeding management, dogs kept indoors live longer than dogs outdoors, and dogs that exercise moderately live longer. Many diseases are the main factors that lead to the shortening of the life span of dogs, especially viral infectious diseases, which have a greater impact on the life span of dogs.

Small dogs: 1. Maltese dogs: also known as Maltese dogs, or translated as "motorcycle angels". With a height of 20 to 22 centimeters and a weight of 2 to 3 kilograms, it is the oldest dog breed in Europe, and is named after the British territory of Malta, a British territory in the Mediterranean.

2. Wave Troubled Dog: Native to Boston, USA. This breed is one of the oldest dog breeds in the United States. It was bred in 1800 around Boston, USA, from horn dogs.

3. Pug: China's native dog breed, is another name for Pekingese dog. At the same time, in various local dialects, it is also known as Shih Tzu, Pug, and their small folded ears crossed with other dog breeds.

Dog age conversion.

The age of the dog is mainly judged by the following points: the growth of teeth; tooth peaks and tooth wear; Exterior color.

1 month is equivalent to 1 year of a person.

Other Age Conversions:

2 months is equivalent to 3 years of age, 6 months is equivalent to 5 years of age, 6 months is equivalent to 9 years of age, 8 months is equivalent to 11 years of age, 9 months is equivalent to 13 years of age, 1 year is equivalent to 18 years of age, 1 and a half years is equivalent to 20 years of age, 2 years is equivalent to 23 years of age, and 3 years is equivalent to 28 years of age.

Formula: first year for dog = 15 years, second year for dog = 10

years, and each year thereafter is equal to 3 years of human age.

One month is equal to one and a half years old.

Extended Information:1Break the age of the dog, check the dog's teeth to know its age. So why do teeth show age? Because among all the parts of the dog's body, the most unconcealable thing is the teeth.

2.The age of the dog is mainly judged by the wear and tear of the dog's teeth. Of course, it also takes into account its facial expressions, posture, fur, etc.

When the dog is 1 year old, all the teeth growth is complete, and at 2 years old, there is.

Some canines have accumulated calculus.

At the age of age, calculus and dirt on the teeth can be clearly seen, and the incisors of the lower jaw are gradually worn out, reaching 5

Around the age of the tooth, the tip of the tooth begins to wear, and around the age of 6, the tooth.

The amount of stones is already quite large, and the canines are beginning to weaken, 7-8

At the age of 10, the teeth begin to loosen, the incisors of the lower jaw will be rounded, and after the age of 10, the incisors with alveolar pus leakage will begin to fall out.

4.Since the lifespan of a dog is usually limited to 15-20 years, we can say that a two-year-old dog is a young dog, a nine-year-old dog is a middle-aged dog, and a 14-year-old dog is an old dog.

5.For some reason, humans have always felt the need to humanize everything related to animals. Since we can't stop the useless behavior of people humanizing animals, we can only put forward these points for reference.
