I could understand how quickly pet parents panic and will rush their dogs to the clinic due to some loose stool but it isn't a serious problem. Perhaps partly because they don't want to clean up the mess or maybe they are truly worried that the cause may be something life-threatening.
Causes Of Diarrhea in Dogs?
However, for the causes of diarrhea, there would be a long list but we'll mention the top ones here.
Blood in Dog Stool : What to Look For?
The next thing to do is to check the dog's tail or the anus. Rectal injury or an infection near the anal area can also lead to streaks of fresh blood.
Thirdly, check the stool if it is normal in consistency (firm not loose), recognize if your dog is acting or eating in a normal energy level. If yes, you can wait the next day to pursue medical action.
Some pet owners basically assume their dogs have hemorrhoids the moment they notice fresh blood on dog stool. But unlike humans, dogs don't get hemorrhoids but are more susceptible to anal gland infections.
This is due to the anal gland in the rectum herniates through the side of the anal sphincter as a result of an infection or impaction.
combined with lethargy and lack of appetite, bring your dog to the veterinarian immediately as this could be a sign of parvo infection.
Bright, red, raw blood in stool
Black, tarry stool
Derives from colon or rectum
Derives from esophagus, stomach, or upper small intestine
In dogs, it is highly likely that the blood comes from the colon or rectal area. Once the dog owner spots blood in stool, the vet should be notified immediately. Hematochezia is a serious condition.
1.) Causes of Hematochezia
Drastic changes such as staying in a kennel, a new dog in the house, or moving to a new place can all trigger stress, hence can cause blood in the stool.
The dog usually develops colitis, accompanied by diarrhea with mucus and blood.
This pathogen is usually found in Dobermans, Rottweilers, German Shepherds, and other black and tan breeds.
Both puppies and adults can contract this virus, but puppies suffer more because of their immature immune systems.
Vets should treat unvaccinated adult dogs and puppies to prevent fatal outcomes.
If the poop is coated with blood, the dog could have rectal polyps, which could protrude from the dog’s anus. These polyps bleed easily.
The vet could feel them when they perform rectal examination. Polyps could also be internal, confirmed by an endoscopy. These polyps may be cancerous.
Dietary Indiscretion or Diet Change
Diet indiscretion including overeating can irritate the colon. This causes the dog to have bloody stools with mucus and diarrhea.
If you also change the dog’s diet abruptly, they'll have similar results, along with vomiting.
It is best to change the food gradually over several days.
Human food, allergies, and spoiled foods can also cause this and colon inflammation.
A dog may ingest a sharp object such as a stick or a bone. The said object may scrape the rectum or the lining of the lower part of the colon as it joins the feces.
It may protrude from the feces once the dog defecates. Once the object is out, the bleeding stops eventually.
Look for any protrusions, swelling, or injuries around the anus or anal glands.
These are the most common causes of hematochezia. Coccidia (protozoan), roundworms, hookworms, and whipworms usually cause blood in the stool.
Once the vet identifies the right parasite, the proper de-wormer can help eliminate these organisms.
Hemorrhagic Gastroenteritis (HGE)
This condition manifests through abundant amounts of blood in the stool, accompanied by diarrhea and vomiting.
The vet would treat the dog with proper medications and intravenous therapy.
Dogs develop allergies to proteins as they become older. Colitis manifests when the allergies become severe.
The inflammation usually leads to the damage of the intestinal tract, resulting in hematochezia. The dog owner should consult the vet to resolve this health issue.
This is an uncommon disease, which can be fatal if not addressed early on. The dog’s immune system eats up the platelets responsible for proper clotting.
This then brings forth profuse bleeding. Other cases result in the consumption of the red blood cells, leading to anemia.
The gums of the dog usually appear pale and not pink. The dog owner should seek vet care immediately.
2.) Causes of Melena
Black colored stool within 72 hours after surgery means that there could be internal bleeding.
The dog owner should bring the canine patient back to the vet immediately.
Giving Pepto-Bismol can make your dog’s stool tarry temporarily.
Gastric bleeding is a common side effect of this medication. As soon as the dog stops taking it, the stool color returns to normal.
NSAIDs (Non-steroidal Anti-Inflammatory Drugs) like aspirin can develop ulcers along the dog’s digestive tract.
Bleeding ulcers are manifested by black stools.
Blood has already been digested and has gone through the dog’s stomach. The dog owner should bring the dog to the vet immediately.
Ingestion of Blood
Licking some blood from a wound or eating blood stew can make a dog’s stool appear tarry.
It is always best to bring the dog to the vet to be certain of the real cause.
Blood Clotting Disorder
When the dog suffers from blood clotting disorders, the tarry stools may be accompanied by purplish skin.
The color change indicates bleeding underneath the skin.
A common cause of clotting disorders in dogs is the accidental ingestion of rat poison. If this is the case, bring the dog to the vet immediately.
Tumors / Cancer
This is common in senior dogs. Once the dog owner spots dark stools coming from their pet, they should see the vet right away. This is to rule out bleeding polyps or even the possibility of cancer.
