Generally, this phenomenon is normal

Sometimes we see dogs often shaking their legs or twitching a bit while sleeping and may think this is abnormal. It might be caused by discomfort in the dog’s body, which often makes one nervous. However, usually, it is just a normal physiological behavior of dogs, so there is no need to worry too much.

In fact, not only dogs, even we ourselves sometimes twitch our bodies while sleeping. Sometimes we even feel like we are falling from a height, which is also a normal sensation. Although dogs sleep for a long time, most of that time they are in a light sleep state. When they are no longer disturbed by external factors, they may enter a deep sleep state. At this time, leg shaking or twitching may occur. However, if a dog shows this issue while awake, it is best to pay more attention. Twitching during sleep is usually involuntary. But if it happens when the dog is awake, it may be caused by a calcium deficiency. (Besides low indoor temperature)

Because the duration of deep sleep in dogs is not very long and most dogs are quite alert, even with their eyes closed, they still perceive the outside world. This is also why some dogs like to press their ears against the ground while sleeping, which helps them quickly detect external abnormalities and react. Therefore, we rarely see dogs shaking their legs while sleeping, and there is no need to be overly worried about this behavior, as it does not affect the dog’s health.

Usually, pay attention to exercising the dog more and exposing it to sunlight appropriately, which greatly benefits the dog’s calcium absorption. Do not always keep the dog confined in a cage; even companion dogs should get enough exercise to avoid obesity or poor physical condition.
