Dog
Often, sellers in pet malls will tell buyers about dogs However, not all sellers will tell the truth. Many times, in order to complete the transaction, the seller will often falsely report the age of the dog. To master the method of determining your dog's age, you only need to do the following four things.
1. Examine the condition of teeth
Dogs generally develop deciduous teeth ten days after birth, and begin to grow after two months. The incisors, canines, and molars are gradually replaced by permanent teeth. A 10-month-old dog can have all of its permanent teeth replaced. However, it will take another 8 months for the teeth to grow stronger and stronger. Common to humans, the older the dog, the more serious the wear of its teeth will be. However, the degree of tooth wear can only be used as a reference for estimating age, because if the dog often eats soft food, then the degree of tooth wear will be smaller.
The specific situation is as follows:
| < p style="text-align:left;">19-28 days old | Eruption of primary incisors | 21- 28 days old | The third milk premolar erupts |
21-35 days old | Primary canine teeth erupt |
21-42 days old | The 4th milk premolar erupts |
28-42 days old | The 2nd milk premolar erupts < /td> |
2 months old | All deciduous teeth are aligned |
3-4 months old< /p> | Replace the 1st and 2nd incisors, and the permanent incisors will grow out |

2. Hair reveals age
As long as the dog’s hair is not white, you can check whether they have The age of a dog can be judged by the growth of "grey hair". Generally speaking, the hair around the lips of a dog around 5 years old will begin to turn white, and then gradually spread to the entire face and back of the dog's head. % of the hair will turn white, and if all the hair on the head turns white, it means that the dog is at least 13 years old.
3. Identify based on body posture< /p>
Young dogs are as light as a swallow and lively and active. They will not be deterred by obstacles. Most dogs will try to overcome obstacles when they are over 5 years old. They will not be as exaggerated as they were when they were young, and all their behaviors will be focused on safety, so dogs of this age will often maintain a calm behavior state, while older dogs over 10 years old will appear more clumsy, and some dogs will also appear. You can tell the difference at a glance when there is a bent back.
4. Eyes can’t deceive people.
Puppies’ eyes are particularly clear and free of impurities. Just blinking your eyes can make you cute. In contrast, the eyes of young dogs are more sharp and clear. Cataracts may appear in dogs over 8 years old.The chance of cataracts is higher. According to the latest survey, dogs over 10 years old will suffer from cataracts. In addition, the eyes of puppies and young adults react quickly to stimuli, while the eyes of older dogs respond more slowly.
Finally, buyers need to pay attention to the fact that everything is different. The above four points can only be used as a reference to judge the age of the dog. Special treatment is required when encountering special situations. Don’t be too entangled. These evaluation criteria.
