In life, we often hear that the one -year -old of dogs is equal to the seven -year -old mankind, but this calculation method is too simple and not accurate. Therefore, zoologists have obtained a relatively reasonable dog age computing algorithm after a large amount of data search. It was found that they grew fast when they were young, but the speed of aging was slow, and in general, small dogs were generally longer than large dogs. 1. The hair becomes white In addition to excluding the dog's natural hair with white hair, under normal circumstances, if the hair on the dog's mouth starts to turn white, it means that the dog slowly enters the old age, and then slowly slowly, and then slowly slowly Slowly extend to the entire face and back. If the hair of more than half of the hair on the head of the dog becomes white, it means that the dog is as high as 10 years old. 2, dental calculation algorithm Most people use this method. This is more accurate. It is the basis of dogs, so this is an important criterion for judgment. There is no teeth within 20 births of puppies. After about 20 days, the teeth began to germinate slowly. Generally, the puppies have 28 teeth, and a total of 42 teeth. 3, the body function decreases The dog bones when you are young are very strong and light. But when they are two to six years old, some dogs will have some awkward action, but they are still stable and safe. After the age of ten, dogs are aging dogs. They will decrease to varying degrees with their own physical mechanisms, as well as physical functions. matter. 4, the eyes become turbid m puppies' eyes can make people feel pity, and the eyes of dogs when they are young are clear and bright. When the dogs entering the age of age, the eyes will begin to dry, tears will appear at the corner of the eyes, and then the eyes will become turbid. The owner can often help the dog wipe the eyes to keep it clean and tidy. 5. Dogs with a slow facial expression are about 1 year old, with active expressions, eyesight, and active; while 2-4 years old dogs love to be close, enthusiastic and enthusiastic; elderly dogs larger than 7 years old, elderly dogs, The spirit is slow, the reaction to the stimulus is slow, unwilling to move more, and the eyes are godless. The dog's life for just ten years, as a master, you have to take care of it. Daily diet should be regular, feeding should be regularly quantified, and healthy foods should be selected. Do not feed dogs to eat high salt foods (such as leftovers, ham, etc.). Dog food can choose light natural food, which is good for health. Just like "non -greasy natural dog food", low oil and less salt, containing deep -sea fish oil and trace elements, it can help dogs with beautiful hair and supplement the body's nutrition.
The wear and drop of teeth. After the dog was born, the milk teeth were born ten days. After two months, the tooth, canine, and molars were gradually replaced by the door tooth, the canine, and the molars. It was replaced by the permanent teeth for 8-10 months, but the teeth needed to grow solid after 1 and a half years old. The puppy swallowed the milk teeth, because the milk teeth are soft, and the dog's gastrointestinal can digest it. Rely on the teeth to estimate the dog age form.
Pay content for time limit to check for freenThe answer can be judged by the dog's teeth, but it is only a rough range. The dogs of 1-6 months are deciduous teeth, and their teeth are pointed and small; 6 months-2-year-old dog's teeth are fair and white, without any plaque; The dog's teeth are yellowed at the same time. At the same time, the dogs over 8 years of age are severe, the teeth are severely worn, and the bad breath and even the teeth have begun to fall off.n2. The change of facial expressions is about 1 year old, with active expressions and vivid eyes. The 2-4 -year -old dog is kind and enthusiastic. Old dogs older than 7 years old are late, react late to stimuli, unwilling to move more, and have no eyes. 3. The change of the body when the young dog is active, and the activity is a bit clumsy at the age of 2-5, but it is stable, safe and reliable. Elderly dogs over the age of 10 have a late manner, the back of the back or flexion, walking slowly. 4. The occurrence of old hair refers to the appearance of gray and white hair (that is, the original non -gray hair dog becomes gray -white hair), which first occurs in the lip area and lower jaw area. The 4-5 -year -old dogs began to see a few white hair, which increased significantly at the age of 5-6. Afterwards, it was extended to the back, around the nose, eyelids, eyebrows, etc., and further expanded to the long white hairs in the forehead and the outer ear canal, and even The entire head is white. There are a large amount of white hair in front of the dog's forehead, face and head. The entire head of more than 13 becomes white (when there are also individual dogs 10-14 years old, the hair color remains unchanged). For dogs with white, yellow and white hair, or maroon -colored white spots, it cannot be used as an auxiliary means to judge age.
The hair around the dog's mouth will turn white first when it is 5 years old, and then slowly want to extend the entire face and back. If 70%of the hair of the dog's head has turned white, it means that the dog is over 10 years old and if the head becomes white, it means that the dog's age is almost 13 years old.
