How is the puppy's hind legs shaking?

The weather was hot and cold, and suddenly it became cold, and the floor was cold. Your dog's feet lie on the ground for a long time, or lie on the ground. It's normal to suddenly tremble because it's too cold. You should put a warm kennel for your dog to avoid catching a cold.

The dog's leg was injured, probably because of fighting with other dogs, and the leg was injured by the opponent. Pet owners should have a good check to see if the dog's legs are red and swollen, touch its parts and feel pain.

It may be arthritis, especially in large and medium-sized dogs. Improper feeding, improper exercise, etc. will make dogs suffer from this.

Dog hind leg trembling may also be caused by long-term calcium deficiency, especially some pet parents just give their dogs dog food, which is not rich. After a long time, dogs will have problems. The manifestations of calcium deficiency are dog leg deformity, X-leg, O-leg, and trembling from time to time.

Dogs live in a humid and cold environment for a long time, or when the temperature is low, they don't take enough care of their joints, which leads to rheumatism. When a dog is sick, his joints will ache and tremble, which may be the front leg pain or the back leg pain, especially when it is rainy and cold every day.

Introduction:

Tremor refers to the trembling of the body due to fear, anger, cold and other reasons.

Basic concepts:

Tremor is a function of human internal environment control system. There is a tiny brain tissue behind the eyes, called hypothalamus, which is responsible for controlling body temperature. Tremor is a way for the hypothalamus to keep the body warm. When the body gets cold, trembling can make the body release energy (on the contrary, when the body gets hot, trembling can make people sweat).

When a person has a fever, the signal from the hypothalamus will further heat the body, thus trying to kill harmful bacteria. This process is like this: the body contracts the subcutaneous blood vessels close to the skin, while other blood vessels relax, allowing blood to flow to the infected site. Blood is therefore far away from the surface of the skin, so you will feel cold. In order to replenish calories, the thyroid gland will start to contract muscles, which will lead to trembling.
