BAD DOG!

Erin
I am almost 34 weeks with our first child.. our normally SUPER well behaved dog has been acting out. He has been scratching at the furniture, chewing things up, and getting his front paws on the kitchen counters! He has never acted this way before (he's 6). I know he feels that something is changing but how do we help him?!
Has anyone else had these issues with their dog? If so, what helped?
