How long can dogs live? How to make dogs live longer? Does obesity affect anything?

What is the longest life span of a dog? Seven years after the birth of small or medium-sized dogs, or five years after the birth of large dogs, they have gradually entered old age. In order to let the dog spend his last life happily, the dog owner should do something for it. In terms of dog health, the calculation method of dog life span: Compared with the calculation method of human life span, the age of dogs is equivalent to 17 years after birth, 23 years after birth and 28 years after birth. After that, the conversion of four years old will be increased every year. So the age of 10 dog is 55 years old. Recently, due to the improvement of nutrition, the life span of dogs has also been extended, and some dogs will live for 20 years. The life span of dogs often has different results because of different breeds of dogs. The difference between dogs and people is that the time after old age is very short, and dogs can live a healthy life six months before they die. Dogs in old age are more active than people, but compared with young people, they often get sick, such as lifestyle diseases or cancer, and some diseases that are difficult to treat. If not treated in time, it is also very troublesome for dogs or dog owners. Therefore, it is necessary to take the dog to the veterinary hospital for a health check every six months in order to find it early. Dogs in old age will have weak eyes, nose and ears, and their activities will be slow. Walk with the dog's speed, and the speed should be slower. If the dog will encounter something very close when walking, then the dog may have cataracts, and it is necessary to discuss eye drops or surgical treatment with the veterinarian in advance, and the temperature is difficult to adjust. Therefore, dog owners will have to spend some energy on regulating their body temperature, and it is also necessary to keep warm when sleeping. It is also necessary to review the replacement of blankets or wrapping the whole kennel with blankets, or using greenhouses for dogs. Pay attention to heatstroke prevention or heatstroke in summer. For an old dog who is exhausted, these are all life-threatening issues. Be careful not to expose the dog to the sun for a long time, especially it is forbidden to put the dog in the car. There is a popular saying that the age of a dog 1 equals the age of a person 7 (or 6). Often 1 8-year-old dogs are considered to be equivalent to the maturity of a 56-year-old middle-aged person. However, a recent survey by the Royal Veterinary College proved that this statement has no scientific basis. According to a survey conducted by Professor Michel, President of the Royal Veterinary College, the average life expectancy of all kinds of dogs in Britain is 1 year and1month, respectively, while those dogs who died completely of aging and were not affected by abnormal factors can live for 12 8 months on average, and only 8% dogs can live to be over 15 years old. Of course, the average life expectancy of different kinds of dogs will be different. For example, a small poodle can live for 14 years and nine months on average, and a long-haired Scottish shepherd can live for 13 years on average. The German shepherd dog, which is often used as a police dog, is 65,438+00. The Great Dane, like a pony, is the shortest-lived large dog. Mixed-breed dogs usually live an average of eight years and five months longer than purebred dogs. Heart disease has a greater impact, accounting for about half of the deaths. Unexpectedly, euthanasia decided by human beings is the leading cause of dog death, accounting for 64% of all deaths. Dogs are usually executed because of illness, injury or "dogs are full of trouble" in shelters. There are too many and complicated factors that affect the life span of dogs. Dogs mature fastest in 1 year, which can be equivalent to 2 1 year of humans. Next, the growth of dogs will obviously slow down, and after every 1 year, the degree of maturity or aging is only equivalent to about 4 years of human beings. According to this theory, the method to estimate the physical maturity of 1 8-year-old dogs should be: 2 1+7×4 = 49, which is roughly in the state of 49 years old, not 56 years old of 7×8. This calculation is more in line with the fact than the arbitrary "dog's life 1 year equals human's life span of 7 years". Of course, proper exercise and nutrition can make dogs enjoy a natural life. In addition, life span is not unrelated to body shape, and it is generally relatively small.
