Fur baby jealousy..

Anyone else having issues with their dog since baby was born? I have two dogs. The mini aussie, five years old, used to be so well behaved and he went everywhere with us (still goes most places unless it's too hot). Since our daughter was born he pulls when on a leash, whines in the car, has to be told more than 3 times to do anything. You might think "he's a dog, what do you expect" but he really was so good and now he isn't. We treated them like our fur babies and still do but he is so jealous of her. When she was first born he loved and protected her. He wouldn't let anyone besides my husband and I near her. It was a little before she started crawling that he got weird. Anyone else? Does it stop? I just want him to love her and behave :(
