It is parvo. My dog had the same thing we were too late and he died of parvo. Go to the vet fast
Why Won't My Dog Eat Or Drink Anything? She Has Also Thrown Up White Mucus Looking Stuff Three Times. Twice Back To Back And Once A Few Hours Before That.
Thanks for all the answers. We took her to the vet, and it was just an intestinal infection. He gave her three shots and about a week or two worth of medicine. She's got a little of her energy back, and is drinking water. She still won't eat anything, but he said give her a few days, and if she isn't back to normal then to bring her back.
Could be something like Parvo, take him to the vet as soon as possible.
Try giving it a laxative
Take here to the vet your dog is definitely sick!
