How are your animals acting?

Monica • had a little girl 11/14/15 & now were on.baby #2 very excited :)
Since being pregnant my dog hasn't acted all loving as they say animals do..he seems to annoy me more (prob hormones) and do more horrible things it's like he is acting out I'm not sure what to do about him anymore I am about to give him to my mother he's just too much..and I definitely can't handle him acting this way and having a newborn and he doesn't seem to get better .. He's very smart and knows right from wrong and is trained generally..like he knows he shouldn't be going in the house and he knows sit this and that crate trained .. I don't know what the issue is :/
