Due to the sudden and frightening onset of AHDS in dogs, many owners wonder how long it will take for their dog to recover. Though each case will vary based on how sick the dog was when they made it to the vet for treatment, there is a general recovery timeline.

Ideally, your dog will not leave the hospital until they no longer have blood in their stool.
