twitching and shaking when asleep
My shih tzu is almost 3 months old now. When he's sleeping, I notice that he has facial tremors and his entire body shakes, and it's not cold.
What could be the problem?
As long as this is only happening when he's sleeping, and he has full and normal control of his muscles when he's awake, then it is most likely nothing to worry about.
Puppies dream when they're asleep, just like we humans do, and their eyes twitch, their faces move, even their legs may move and they often whine or cry, or even bark. It's all normal.
If your pup has any difficulties when he's awake, or he seems to be sick in any way, then have him examined by your vet right away. Otherwise I don't think you need to be concerned.
Best of luck.
