Wearing your baby is a good idea, providing that your LO likes to be worn! My LO will sometimes tolerate being worn, but will often scream her head off when I try to put her in her wrap.
My advice is to play it by ear with the dog. I have an 80 lb German Shepherd, and I didn't want to separate her from us, but I also was really nervous about having LO in anything that was accessible to the dog. For the first few weeks, I prety much held LO if she was not in her pack and play or crib, and I honestly didn't get a whole lot done around the house (which is ok! paper plates and takeout are your friends!). The dog loves the baby, though, and is very gentle with her, so I realized after awhile that it would be fine to have the baby in the bouncy seat while I do dishes, prepare/eat a meal or take a shower (I put the bouncy seat right by the glass shower door so I can see her). The dog might come up and sniff or lick the baby, but that's NBD and she will back off when told to.
So, a lot depends on how your dogs do with the baby. Mine reacted as well as I could have ever hoped (she was very happy when the baby came home and has been an angel as far as interacting with LO and respecting her space and toys). Even so, I would never leave them alone in a room together. But, I have no problem having LO on the floor or in the swing or bouncy seat when the dog is in the room, as long as I am there too.
