We have two dogs, strictly indoor, and they bark a LOT. We've talked to the vet and a trainer, and the consensus is that we might be able to get them to cut back some, but they'll always bark. It's just a territorial-ness issue and probably not going to ever get 100% better. So I'm obviously a little concerned about how that could wind up effecting the baby's ability to sleep. One nanny job I had, the dogs barked a ton and baby never flinched. I think they disturbed her all of once when I was working there. But is that pretty typical? Do they get used to it, since they hear it from day one (or earlier, through the womb)? I know every kid is different, but I'm curious about others' experiences.
