Dog
Under normal circumstances, sellers in the pet market will tell the age of buyers, but not all sellers will tell the truth. Many times, in order to reach a transaction, sellers often report the dog's age. If you want to master the age of dogs, you only need to do the following four things.
1. Observe the state of the teeth
Dogs generally grow milk teeth more than ten days after birth. Two months later, they start to gradually change from the door tooth, canine, and molars. More solid, it takes 8 months. Like humans, the older the dog, the more severe the teeth are worn. However, the degree of wear of teeth can only be used as a reference for judging age, because if dogs are usually soft food, their teeth wear is small.
Details are as follows:
| 19-28 age | milk cut teeth | 21-28 age | The third milk anterior molars grow family | milk canine teeth grow | 21-42 age | 4th milk anterior molars grow | 28-42 age | The 2nd milk anterior molars grow | February age | All milk teeth are long | 3- April age | Replace the first, the second tooth, the permanent teeth grow | 4-5 May age | Replace the first molar with the first milk, the permanent molar grows | 4-16 years old | Replace the canine teeth, grow permanent canine teeth, and the 1st permanent rear molars of the upper and lower jaws grow | 4- July July | Replace the second rear molars and grow permanent teeth | 5-19 June | Replace the third tooth and grow permanent teeth | 5- July July | 2, 3, and 4 permanent forward molars | 6-15 | The 3rd permanent rear molar grows | 9-1 October | All permanent teeth are replaced | 1 year old | Permanent teeth are long, white, bright, and cut teeth | 1 and a half years old | The tip of the 1st tooth is worn | 2 and a half years old | The tip of the second tooth is worn | 3 and a half years old | The tip of the top of the upper tooth is worn | 4 and a half years old | The tip of the top of the upper tooth is worn | 5 years old | The tip of the mandibular teeth began to wear, the first teeth of the first and second teeth are rectangular, and the canine teeth begin to wear | 6 years old | The tip of the mandibular teeth began to wear, the catalyst is blunt round | 7 years old | The first cut of the jaw is worn to the root of the teeth, grinding into an oval shape | 8 years old | The first cut of the jaw is worn out and tilted forward | 10 years old | The jaw 2, the grinding surface of the 1st tooth of the upper jaw is oval | 16 years old | 20 years old | Canine teeth fall off |
As long as the dog's hair is not white, you can judge whether they have long "white hair". Generally speaking, the hair near the lips around 5 years old will turn white first, and then gradually spread to the entire face and back. About 70%of the heads of dogs over 10 years old will turn white, and if the hair on the entire head becomes white, it means that the dog is at least 13 years old.
Three.
The young and middle -aged dogs are as light as swallows and lively. They will not be discouraged because of some obstacles. Most dogs will try to cross the obstacles. When the dogs are 5 years old, they will not be as adventurous as when they are young, and all actions are mainly safety, so dogs of this age usually maintain a stable state of action. Elderly dogs over 10 years old seem to be relatively dull, and some dogs will still have a phenomenon, you can distinguish it at a glance.
Four, can't deceive people
The puppies' eyes are particularly clear and there is no impurities. They blink and blink can make you sprout. Relatively speaking, the eyes of young dogs are more firm and bright. When a dog enters the old age, cataract may occur, and the chance of cataracts over 8 years old is higher. According to the latest survey, dogs over 10 years old will suffer from cataract. In addition, the eyes of puppies and young dogs responded rapidly to stimulation, while the response of elderly dogs was relatively slow.
In the end, buyers need to pay attention to everything. There are exceptions. The above four points can only be used as a reference to judging the age of dogs. When encountering special circumstances, special treatment is needed, and these judgment standards are not too entangled.
