Well the puppy needs to know that YOU are the boss not her so make sure she knows that you are the alpha "dog". Put a stop to behavior now that you don't want her to do when the baby comes like getting up on the sofa etc.
If you are going to use lotion on your baby or like a baby bath rub it on your arms so puppy gets used to the scent. Also you could wash a blanket or baby vest in the detergent you will use and put it in the dogs bed so she gets used to the smell.
Get the baby things out like moses basket/pushchair so she is used to seeing them and let her sniff about so she knows what they are and wont be all excited when they appear all of a sudden.
Also when you bring the baby home let her have a look and dont be frantically trying to keep her away from the baby. she needs to learn that this "thing" is something that will always be there but isnt really anything to worry about.
I know its cruel to think about it now but you have to start being more distant with your dog now so that she isnt used to being attached to your hip all the time and getting lots of attention so she isnt jealous when baby comes.
We did that with out dog before our daughter came and he doesnt really bother with her at all! He will sniff her and maybe lick her then walk away!
I would google it to get more info as there is so much on the net about it.
Good luck x
When.baby gets here I think she will become just as attached to.the baby as she is you. She will recognize you love the baby and she will grow to love the baby too
You can get her use to a crate and if you have time/money, obedience classes. If she acts like tjat when you're busy doing dishes, she's probably goung to start tearing things up when you leave the house for what she feels is too long. She should be pretty good with your new comer bc she does seem loving, just make sure you give her your own temperment test so as the baby gets older and may be rough or try to put hands near the dog's food, you will already know if it's something to constantly watch over and redirect your child, or something you just need to watch put of the corner of your eye
We got a small dog right before my second daughter was born. She is min pin and chihuahua mis. She got very attached to me before baby and now she constantly wants attention. And when I ignore her or dnt play w her she like to tear everything up. Especially toilet paper! Lol but as far as baby goes she is really good w her and has never snipped or bit her. She jst licks her too death. But if I were u I wld def give some space between u 2. Cause if she is anything like my dog when we came home from hospital she was WIDE OPEN!! LOL and wanted to play soon as I was home. But good luck and trust me, better sooner than later:))
