> good food for Mum though, as nature intended.
Very true - all small animals eat theirs, and with most of the small animals we can't be there to prevent it. It is one of the wonders of nature that a totally vegetarian animal such as a rabbit, will eat the lot. I've seen them eating it, it's like the mouth says Nooooo.... but the brain says Yessssss... and the bunny-mum has a totally glazed expression like she's high on drugs. Stepford Rabbits!
Pity the rat-mum who may have to eat up to 20.... But this is a way of making sure the new mum has food and sustenance and doesn't have to go out grazing, foraging or hunting for a day or so, thereby risking herself... and giving her much-needed time with her newborns.
OK so I have never bred dogs BUT have bred cats and as long as I can count the placentas, I have no issue with mum eating them whatsoever. It's how it's meant to be, whether you are there or not. Cat mothers and Dog mothers have done this for thousands of years, I just can't see why it would be negative.
PS: The loose stools may not be from eating the placentas, but a natural effect after the birth anyway.
