Thanks so much for the replies so far. We did get a CD with a baby crying (who would have thought there would ever be a market for that?-another missed opportunity there.)
Most of the dogs perked up their ears and started pacing, but no barking and stuff yet.
Blankets with the scent are a good idea.
I just don't want to have to
rehome the baby after he's born because our little Houston tries to eat him.
Hahahahahaha.
