Hi! You may know that we adopted Bernie from a rescue a few weeks ago. Well, he's an awesome dog and we love him bunches.

He has one behavior that concerns me though and I wonder if anyone has seen anything like this.
In the evening, he'll go lay on one of the dog beds, wrap his front paws around one side and put a large part in his mouth. He doesn't chew or even suck on it, he just holds it in his mouth... and tightly between his arms and goes to sleep.
could this be a sign he was taken from his momma too young?

Something else? or am I just being paranoid???
