Hello and welcome to Petco Pet Education Center, formerly Petcoach. Spasms can be caused by many different things. Firstly, sometimes puppies will twitch in their sleep, and this is dreaming. If the muscle spasm is only in the left leg and continuous, it would be more concerning for pain in that leg. If that is the case I would have it checked by your vet to see if there is a luxating patella or soft tissue injury that is causing pain. Other causes of muscle spasms include toxins, neurological diseases/disorders, and metabolic conditions. If the spasms are very mild and intermittent then it might be behavioural, but if it is continous or severe, then I would have Coco seen by a vet right away. Best of luck with Coco.
