my sisters yorkie was seen at a local emergeny vet for rectal bleeding, they sent her home with some antibiotics saying that it is a common gastro intestinal problem in little dogs, the dog is severely dehydrated, but my sister couldnt afford the 500 dollar payment for the emergency vet to keep her. the bleeding is now getting worse and my sister dosent know what to do, the blood comming out of the dogs rectum now looks like it has coffee grounds in it. any help would be appreciated
