Poor baby, hang in there I know as a mom you feel so helpless when there's nothing you can do for them. Your pup is gorgeous. I actually work with a lady who breeds and shows akita's. I'm assuming from the picture that's what Sheba is. Take care and I'm sure it's maybe something as simple as she got into something and the mixture of the heat that maybe has caused a little bacteria bug in her tummy. good luck!
