Why does my puppy twitch while sleeping?

Twitching while sleeping is very likely because the puppy is dreaming; when it runs or jumps in its dreams, it may twitch. This is normal and the owner need not worry too much.

Second, it may be that the puppy just arrived in a new environment and feels unfamiliar and afraid, causing it to twitch during sleep. In this case the owner needs to give the puppy enough sense of security.

In addition, this behavior may also be caused by calcium deficiency, so the owner should feed the dog a nutritionally balanced diet to prevent nutritional deficiencies.
