My toy poodle is close to whelping. We're on day 57 and we're having 4 puppies. We had her to the vet yesterday for an xray. Today we noticed her vulva looks like there is a hardened crust on the exterior of her labia which appears to actually be stuck shut. She apparently started a little discharge. I would love to place her in a warm water bathtub for a little soak to loosen that up. No scrub, no soap. She usually loves her bath. Does this sound ok?
