An inflammation of the colon can be accompanied by blood in the stool. The symptoms can suddenly start, the dog or cat can have an increased pressure and continue to press. Such a problem is annoying and painful.
With a good examination and targeted treatment, (quick) recovery is often possible.
An inflammation of the colon
Inflammation of the colon (colitis) is the most common cause of blood in the stool.
A dog must also often defecate in the case of a large intestine inflammation, for that reason possibly poops in the house and continues to squeeze when the intestine is already empty. Besides bloody, the stool is often also slimy. Sometimes the dog only bloody mucus. The blood is fresh and red.
If your dog has these problems, it is good to worming your dog. You can also start with the local anti-inflammatory and painkiller salazosulfapyridine. This medication provides clear relief within 24 hours in most cases.
If the problems do not go away or keep coming back, further research (physical examination, stool examination and a visual examination (colonoscopy) should be considered.
Bleeding from stomach and small intestine
Small bleeding of the first part of the intestine (the small intestine) or the stomach does not cause a different color of the stool.
When there is a major loss of blood in the stomach or small intestine, the stool turns black (melena) and the faeces stink.
If your dog has no bleeding in the skin or mucous membranes and the problems only seem to be in the intestines, an ultrasound and / or visual inspection of the intestines is recommended.
Acute haemorrhagic diarrhea syndrome (AHDS)
The old name of AHDS is haemorrhagic gastroenteritis (HGE)
Dogs with AHDS become seriously ill one after the other. Apparently the dog will surrender out of nowhere. The vomit often contains blood. A few hours later the dog gets watery and bloody diarrhea. The clinical condition of the animal is rapidly deteriorating.
Most dogs are carried in by the owner.
In blood tests, the animal appears to be severely dehydrated, while it is striking that the amount of red blood cells seems to increase despite the bloody diarrhea.
With good treatment, the chance that a dog survives AHDS is very high.
In a study by the University of Munich, 97% of the dogs treated survived.
Dogs with ADHS are treated with large amounts of infusion. Sometimes a blood transfusion is required.
The treatment is very intensive and therefore only possible in a clinic that is equipped for this :
– infusion through the blood vessels.
– knowledge of the different types of infusion fluid.
– nursing available 24 hours a day.
– a sufficiently equipped laboratory.
A treatment usually lasts for 3-5 days.
Although the syndrome is probably caused by (the alpha toxin of) the bacterium Clostrium Perfingens, giving antibiotics has no added value and dogs in the immediate vicinity of the patient are generally not sick.
Polyps and colon tumors
Polyps and intestinal tumors are found in particular in older dogs.
In most cases, the polyps or tumors can be felt in rectal examination. When in doubt, a colonoscopy may be necessary to make the swellings visible.
In many cases it is possible to surgically remove the polyp or tumor.
