Deer dolls refer to younger deer. In some areas, in order to distinguish the age and sex of deer, the tail is cut off when the deer doll is born. This behavior is called "tail cutting" for the following reasons.

1. Identify the age and sex of deer.

In the wild, it is difficult to know the age and sex of unmarked wild animals accurately. By cutting off the deer's tail, it is easy to distinguish between age and sex, which is beneficial to scientific research and wildlife protection.

By cutting off the tail, breeders and protectors can easily judge the age and sex ratio of different groups of deer. In this way, we can better grasp the structure and dynamics of the population, raise young deer, protect and reproduce.

2. Narrow the range of deer activities.

Another important function of tail cutting is to reduce the range of deer's activities. The deer's tail is flexible and can swing at will. In the natural environment, deer balance their bodies through their tails, and can also play a balancing role when jumping.

However, in farms and zoos, the deer's tail will wear and damage the fence, causing the deer to escape, get injured or cause other injuries. Cutting off the tail can reduce the range of action and the possibility of escape of the deer and ensure the safety of the deer.

3, in line with cultural traditions

In some areas, cutting deer's tail is still a traditional cultural behavior. For example, in the northwest of China, Pakistanis traditionally think that deer is a sacred animal, and tail cutting is an act to protect deer. Therefore, they usually cut off the tail of deer dolls to show respect.

In other areas, such as Canada and Egypt, deer tail cutting is also influenced by certain culture and is regarded as an important and necessary means to domesticate and manage wild animals.

4. It has little effect on the animals themselves.

Although tail cutting is a controversial behavior, from the point of view of clinical practice and animal protection, it does not have much impact on the health and survival of deer.

If carried out under professional medical care, tail amputation usually does not cause long-term pain and suffering to deer. After cutting off the tail, the deer will restore the function of its tail and can move, eat and survive normally. Therefore, deer tail cutting can be regarded as a necessary measure to protect deer's life safety and strengthen wildlife management and protection.
