I bet at least 2-3 times a day one of the chins will let out a bark in their sleep.
I don't see why they wouldn't dream.
Funny thing is it could be one of a pair doing the barking, and the other doesn't make a move from their sleeping pile.
So why ever they do it never seems to bother any of the others.
Jenova,
I'm sure you'll figure out in time why your chin does or says what he does.
It's hard to tell what they are getting on with unless your there. Every chin is different, and every set up is so different. That's why we always say to get to know your chin, and keep a good routine going.
It's so much easier to spot problems, or interpret what the chins are saying and doing.
