You sound like a very sweet mommie. I need to caution you of reasons she may have loose stool. It is very common for puppies to have worms, etc, but you should also have the vet check her for giardia, as this is transferable to humans and you should not have her in your bed
I'd have a stool sample tested as soon as possible. Hopefully, I'm wrong, but remember it's treatable but you need to tend to it as soon as you can. Good luck!
