Home remedies and their effectiveness

You shouldn’t try to treat a dog throwing up blood at home, as many causes can be life-threatening.

If your dog has started vomiting blood, it’s best to see a vet. Even the ‘mild’ cases caused by stomach inflammation do need medical intervention to help them settle down. Many causes are more severe and some can be life-threatening, so it’s best to let your vet make that assessment.

However, simple home care when your dog first starts vomiting can prevent them progressing to throwing up blood. Removing food for several hours allows the stomach to settle. You should then re-introduce small amounts of a bland diet little and often so as not to overwhelm your dog’s stomach. This may be enough to stop your dog from vomiting, but if it’s ineffective it’s still recommended to see a vet.
