Hello and welcome to Petco Pet Education Center, formerly Petcoach. Having a vomit or two after deworming can be normal, however if it continues or if Kain is acting weak or tired then I would get him to a vet right away. Puppies often twitch in their sleep, and they are dreaming. You can try waking him up during this twitching, if it stops right away it was just dreaming, if it continues it is a seizure or twitching that needs to be seen by a vet right away. Best of luck with Kain.
