Dogs Pooping Blood


Dogs pooping blood is a serious condition. Dog owners should take their pets to their vet if this occurs, or at least call them. Typically, parasites of some type are the cause. Other causes are stress, change of diet, swallowing a sharp instrument, or serious digestive problems. Regardless, it is considered a health risk for your dog.

Any change in dog stools that causes blood to develop from inside the anus and rectum is a red flag. It always involves color, consistency, and the frequency of the dog’s stools If the feces is dark, black or tar-like, it is a matter of concern there is blood in the dog stools. This should be a double flag requiring a quick call to your vet.

Dogs pooping blood in any color of feces other than brown means there can be digested blood located somewhere in the dog’s gastrointestinal tract.  Repeating myself,  bloody feces in dogs can be caused by bleeding ulcers, foreign objects, colitis or anal gland conditions. This is something that cannot be stressed enough.

Dog owners spend over half their lives knee-deep in dog poop for one reason or another. We become so conditioned to it that its a normal part of /our life, especially if we run a shelter, a large kennel, or a foster home for unwanted pets.

When dogs poop blood, I generally look for dog worms at the get-go, especially if the dog is new.  I routinely worm my own dogs, but if I find blood in dog poop at my place, parasites or dog worms are never ruled out as there are so many types of dog worms and parasites. The affected dog is taken to the vet for a fecal sample right away.

Dog worms that are most apt to cause the condition of dogs pooping blood are hookworms and whip-worms. Whip-worms are accompanied by bleeding rectums, slimy bloody stools, and anemia.  Hookworms, on the other hand, cause bleeding stools and anemia, not slimy stools or bleeding rectums.

Health risks for dogs pooping blood

  • Black stools – sometimes black stools are caused by the dog or puppy consuming Ibuprofen or Motrin, causing a serious toxicity (poisoning). This is accompanied by pale gums, large amounts of digested blood, and a low red blood cell count.
  • Coccidiosis – this is an intestinal disease that primarily affects puppies, kittens, canaries and human beings. A parasite that lives in the wall of the intestines, it causes a water, mucous–based diarrhea. In puppies, it can be fatal if not treated. Without treatment, it damages the lining of the intestinal tract.
  • Dyschezia – constipation associated with a defective reflex for defecation in dogs and young children.
  • Dog diarrhea – loose feces, dog diarrhea is the most common problem that affects dogs. If it is accompanied by loss of appetite, marked lethargy, frequent vomiting, abdominal pain, and lasts longer than 48 hours … medical attention is required.
  • Hematochezia – the passage of bloody stools, Hematochezia involves a passage of fresh blood through the dog’s colon or rectum. It is more commonly referred to “bright red blood in the stool.” As it can also be maroon in color, the blood is usually in or with the feces, located in the lower gastrointestinal tract.
  • Melena  – the black, “tarry” dog feces that is associated with upper gastrointestinal bleeding. The black color comes from hemoglobin in the blood, changed by digestive chemicals and intestinal bacteria.
  • Mucus in dog stools –  this can be caused by a variety of dog illnesses and parasites, even though it is not always an indicator of poor dog health. If it is accompanied by blood or a serious change in your dog’s bowel movements, it is usually more serious.
  • Blood in dog stools – Dyschezia and Hematochezia

Blood in dog stools should be a red flag alert that something is wrong, even if you do not know what it is.  But common sense says fresh red blood coming from our dog’s anus is a health problem, and slapping a brightly colored bandage on it will not work.

Two pretty common conditions, other than dog worms,  that involves dogs pooping blood are Dyschezia and Hematochezia. Both involve diseases of the digestive and intestinal system. And both are visible presentations of an underlying disease that causes inflammation or irritation of the rectum or anus.

Dyschezia

Dyschezia refers to a difficult or painful defecation. The word originates from Ancient Greece, meaning to “ease oneself, or defecate.” Dyschezia is usually associated with constipation in young children and newborns who have difficult or painful bowel movements.

However, temporary dyschezia also develops in dogs. Dyschezia in dogs is the inability to have a bowel movement without pain for many reasons. It can be caused by a disorder of the colon or rectum, bowel impaction, bacterial infections, constipation because of an incorrect diet, anal sac infections, allergies, colon cancer, and chronic constipation. The colon and rectum are associated with body elimination, passing through areas formed by the pelvic bones.

Dyschezia can develop because of dislocations and diseases of this area. In male dogs, prostrate diseases can cause secondary painful bowel eliminations, as the colon passes directly over the prostrate gland.

Hematochezia
Canine Hematochezia is the presence of bright, red blood in dog stools.  If the blood accompanies vomiting, lethargy or coughing, the vet can determine the cause quicker, so make sure you observe any abnormal symptoms. Also, the age of the dog has a lot to do with how serious the condition is.

Younger pups or dogs under one to two years are chewers and players, so the cause of dogs pooping blood could be a foreign object it has chewed on with sharp edges, or it could be parasites or dog worms due to inadequate worming. Older dogs get sicker with more serious conditions and they heal slower, so it should be a mandatory vet trip.

    There is a sick dog on my hall in our apt building. This dog is supposedly a service dog. It is a great Dane and the owner is a very small old lady with a walker. She uses that muzzle harness. The dog hardly ever gets to go outside and there is poop, pee and vomit all over the carpets everywhere she has been. Yesterday, my chihuahua (9& 1/2 ) and he had to go out 3 times in about 30 minutes. The last time, he had already had a large poop. Not exactly diarrhea but not firm. The last time, all he pooped was about 15 drops of bright red blood. As soon as we came inside, he promptly threw up. I make his food so I know exactly what he eats. I am on a fixed income so vet bills are devastating n my vet won’t take payments. No one in town will. I have 0 money til the 3rd of January and if he is that sick, I’m terrified of losing him. He is my only family and I’m looking it here. I don’t know what to do cuz even if we go to the vet, that other dog is still sick and there is poop n pea n puke all over the carpets all over the building so even if we go to vet, whatever is making him sick is still on the carpet. I don’t know what to do and I’m terrified. Please help if you can. My email or a text to my phone will work. Please, I don’t know what to do and I’m so scared for my baby. He is just so little. Any advise will be welcomed. Thank you. (No field for ph#) he has no worms in his poop. But I need a fast cheap worm med or something that works for us both. About a year ago, I had a tapeworm (didn’t get it from him. He had none) and I didn’t know that was why my belly got so huge. I had just stopped a med that I was taking for a year or so, lyrical, without the step down, just stopped. Anyway, I was in the bathroom for hours nearly screaming in pain and suddenly felt something very large and long slip out my rectum. There was nothing in the toilet but I had immediately lost almost 15 lbs and my huge belly. I don’t know how I got that worm as my dogs vet had just done what they do with his stool sample and he had no worms. My Dr said probably from lettuce that I didn’t wash well.( I now spray all veggies with white vinegar and garlic then rinse well) don’t know if it works and I do know that when I was small, I had a tapeworm and my mom gave me a spoonful of sugar with castor oil. So now I have added that to my spray. This of course isn’t about me but I was wondering if you know how much castor oil is safe in an adult for worms? I know it is poison, but effective and pharm didn’t know. Thank you

      Could you tell me where you live?

      And do you not have a manager that is monitoring this kind of stuff? If your neighbor’s dog is a service dog and is ill, something needs to be done immediately. Maybe she, and her dog needs some help or something. If you have a nearby vet to contact, ask him who you can contact about the Great Dane.

      As far as your dog and the fact you cannot afford to go to a vet, the blood may be coming from worms attaching to her intestines. No matter what, I would take her to the vet due to her size. You cannot worm her accurately. Do not take her out in the hallway but buy adult chucks or pads at walmart. Train her to use them and do not expose her little body to anything in the infected hallway.

    Any person, dog, cow, bird or related creatures that poop blood has a problem. It is common sense, especially if there is diarrhea and blood combined, possibly with mucous, to go to the vet immediately.

    Yes some is, while the rest is medically caring for dogs since 1999 in our rescue. I combine as much information from the vet, books, online, classes, discussions, etc. that I can. If I was copying from online sources I would not have misspelled terry, now would I?
