:( my dog is 6 yrs and pregnant and has a grayish pink look to her tonge and gums she refuses to eat and she is drinking a lot her pooh is like water but very black what can I do

JLynn, you need to call a vet right now! Your description of her tongue & gums, along with blackness to the stool suggests to me she is bleeding internally. But, we can't examine her here online. You need the help of a qualified medical professional. Please, call a vet ASAP and get her in today!

Call a vet or take her to a vet.
