What is the function of a dog's tail, and how long is its average lifespan?
Dogs are canine mammals found all over the world. They began to be domesticated by humans as early as tens of thousands of years ago, and can be considered humanity's most loyal friends. There are very many dog breeds, and they are the animals most commonly kept as pets, deeply loved by everyone. Every time a dog sees someone familiar, it wags its tail. So what is the function of a dog's tail? How long is its lifespan?
1. What is the function of a dog's tail?
1. Maintaining body balance
When a dog walks or runs, its tail helps keep its body balanced, which is also why they can jump and climb slopes so agilely.
2. Spreading a special scent
Dogs have a strange way of making new friends: they sniff each other's rear ends. This is because a dog's rear end has a special gland that secretes a unique personal scent, and the constantly wagging tail acts like a fan, helping spread that scent farther.
3. Expressing emotions
When a dog is happy, it will keep wagging its tail. Especially when its owner walks over from a distance, it is very affectionate, wagging its big tail nonstop. If a dog is very frightened, it will tuck its tail tightly between its legs, looking very cautious.
Overall, a dog's tail is like another language for it. Different types of dogs have somewhat different tail shapes and sizes, but the meanings they express are much the same.
2. How long is a dog's lifespan?
A dog's lifespan is mostly around ten-plus years, but it varies with different breeds and different ways of raising them. Generally, small or medium-sized dogs have already gradually entered old age seven years after birth, and large dogs five years after birth.
If it is a healthy dog, the lifespan is calculated as follows: generally, one year after birth counts as seventeen years old, two years counts as twenty-three, three years counts as twenty-eight, and each additional year adds about four years, so a dog that is ten years old can be counted as fifty-five in human years. Nowadays, with improved raising standards, dogs' lifespans are a bit longer, and some dogs can live twenty years.
Once a dog enters old age, its senses weaken and deteriorate, and its movements become very sluggish. At this time, we must take care of it with even more attention. When taking it out for a walk, watch out for obstacles ahead, and when the weather is cold or when it sleeps, cover it with a warm blanket. Take it to the pet hospital regularly for health checkups to prevent illnesses from delaying treatment. After all, it is our good companion, and we must care for it attentively. Once you decide to keep a dog, you must not abandon it.
