Aw, congratulations!!!! Your dog is the perfect age to have a new baby in the house. I have posted on other threads that I have no idea how people have children WITHOUT a dog
Mine always laid right underneath the highchair, chin on the crossbar, just waiting for the crumbs to fall
Instant clean up, quite a working relationship!
While the baby is an infant, you will be fine, just remember if your dog is allowed to jump on the bed, you can't lay the baby on the bed and turn your back. All common sense stuff. As the baby becomes more interactive, just keep watching your dog for signs that she is relaxed and not stressed.
If it were me, I might brush up a little on dog behavior and get a book on interpreting signs of the dog being uncomfortable, I am not an expert on this by any means, but there are signs when a dog is 'done' - body stiffens, tail stiffens, etc. Most dogs will try to get away but there are always some who won't.
At the superbowl party I attended last night there was a baby who must have been about 9 or 10 months, just barely walking. The host has a long haired mini dachsie who isn't around small kids much. This baby kept staring, fascinated at the dog and toddling toward the dog. Of course the dog was very unsettled by that strange little person staring at him. Kept barking sharply and backing up. It was pretty obvious he was uncomfortable.
I was lucky that my first golden was terrific with children and I have some unbelievably wonderful photos of him being used as a pillow, and a chair, the time he jumped into the bathtub with my two year old, the time he jumped from the guest bed into the crib with her at my mom's house when she was 3. He used to climb up the slide to get up in the "treehouse" part of their outdoor playset when they were up there. Once I even caught my two year old using him as a step stool to get on the couch he never batted an eye. Of course I admonished my kids that they must never do that again, but he was young and healthy and took it all in stride. (I have 3 daughters so he saw it all.)
Keep practicing obedience and enjoy this time. Can't wait to see the photos you will post of your baby and golden together, they will be wonderful
