gals,
for your infor, cats do have risk cos of a certain bacteria, forgot what's the name but not dogs, the vet told me that and even mentioned that so many vets got pregnant ( still working) and have normal babies too, as per normal, we only have to take care of personal hygiene, that's all. I have a dog too and my gf has 6 dogs, no problem at all.
Higher chance of getting infection from human than dogs, that's why your gynae will always ask you to avoid crowded place.
