my pregnant corgi is about 2 weeks till she is about to whelp. at night, about 2 hours after i let her out and we walk around the block and she does her deeds, she has been getting diarrheas in the middle of the night. i was wondering if maybe i am feeding her to late that it is upsetting her stomach when she eats? or could it possibly be morning sickness because its so late at night her stomach gets upset? could it be that the puppies are getting bigger in her and she cant process her waste into a regular poop? this is my first time experiencing this. its happened about 3 nights already. anybody have any idea? thankss =)
