Blood in dog diarrhea

Diarrhea can have a number of causes, and blood can often be passed within it due to inflammation of the wall of the intestines. In most cases, a small amount of blood in the diarrhea is not particularly concerning, as it just results from inflammation, but if a lot of blood is passed it can be a sign of a more serious problem, and can lead dogs to become weak and dehydrated.

Causes of dog diarrhea

Causes of dog diarrhea include eating rotten food containing bacteria, eating foods the dog cannot tolerate or is allergic to, and picking up worms, other parasites, viruses, or bacteria.

Dog bloody diarrhea treatment

Any cause of diarrhea can initially be treated with a short period of starvation, fluids, and medication that helps to bind the dog up, and rebalances the levels of good bacteria in the guts. It is also important to worm any affected dog who is not up to date with worming treatments.

Dogs who are unwell, in pain, vomiting, or passing so much fluid that they are becoming weak, may need intravenous fluid therapy as well. Further investigation with faecal tests, blood tests, and X-rays or abdominal ultrasound examinations may be needed to identify the problem.
