The tail words of a dog
The dog's tail conveys a certain meaning in the movement, which can reflect its intelligence level, social status and inner feelings. Dogs can shake their tails as early as 20 days old. Generally, there are three channels to convey information: posture, movement and shape. Because dogs' eyes are more sensitive to movement than color and shape, they use tail shaking to convey information.
1. Stiff stretch: generally has the meaning of attack, in the face of strangers and intruders this is a challenging way. It can also be used as a cautious greeting when two dogs who don't know each other meet for the first time. In this case, they are often assessing their chances of winning and often a dog retreats.
two。 Lift up: this is a signal from a dominant dog.
3. The tail droops naturally and swings occasionally: this is a carefree dog, which can be interpreted as "I am relaxed".
4. Tail clip: this position can be understood as "I'm scared" and can help stop other dogs from attacking and serve as a message of peace.
5. Vertical hair on the tip of the tail: this kind of situation is rare, only the hair on the tip of the tail is raised, which means anxiety, fear and unease on the basis of attack.
6. Tail wagging slightly: dogs greet people, generally thinking that strangers, the owner's occasional attention will also be this kind of dog echo, as a sign of friendship support.
7. Large swing: a friendly signal that indicates happiness during dog-to-dog games.
8. Violent swing: when the tail swings violently and drives the buttocks to shake, it is usually a greeting of reunion after a long separation, and the wine will be so excited when the dog's special friend appears.
9. Long swing: this swing is not as easy to understand as other swings, which often happens in training, which can be understood as "I try to understand what you mean, but I really don't understand it yet." When the dog finally solves the problem, the swing of the tail increases significantly, which occurs when the dog is tracking or identifying differentiated odors.

The estrus of the female fox shows that the vulva is covered by pubic hair during the resting period, which is not easy to find; during estrus, the pubic hair is separated due to vaginal swelling. The estrus period of female fox is short, mating is difficult, and the timing of adaptation is also difficult to grasp, especially the empty rate of silver-black fox is higher. In order to improve the reproduction rate, it is necessary to master the oestrus law of female foxes and carry out mating or artificial insemination at the right time. The estrus of female foxes can be divided into three stages: the first stage: the clitoris begins to swell, clitoris enlarges, tends to be heterosexual and sexually excited, and generally continues.
