Rocky is about 9-10 weeks old and he is the only dog I've ever seen sleep this deep. His whole body will shake/twitch sometimes, others he is barking or growling continuingly.. (but doesn't really bark much at all when he is awake).
I had gotten really scared when we first got him... but my bf just told me he's just a big dreamer. Now it's been two weeks. and he's still doing everything the same.
I guess him shaking/twitching could be him running in his sleep?

My last dog had dreams and would run/bark/growl in his sleep.. but nothing like what Rocky is doing! He sometimes has his eyes open... can dogs sleep walk?

Is this abnormal?

Thanks!
