Clear, jelly-like poop with blood in a dog often signals Colitis (colon inflammation) or Hemorrhagic Gastroenteritis (HGE), both requiring prompt vet attention, especially if your dog seems unwell, lethargic, or has large amounts of blood; causes range from dietary upset, stress, parasites, infections to foreign objects. It's crucial to see a vet, as this can be a serious sign of dehydration or internal injury, though mild cases might resolve with bland diets if the dog remains normal.
Dog poop that looks like jelly with blood typically indicates inflammation in the large intestine, called colitis. This needs quick veterinary attention when your dog has multiple episodes of bloody diarrhea, shows low energy, or appears in pain.
Clear jelly-like anal discharge in dogs often indicates anal gland secretion or mild irritation. Symptoms include licking the area, scooting, or discomfort. Causes range from impacted anal glands to minor infections.
Gastrointestinal Upset and Diet Changes
Food intolerance or sensitivity can also trigger excessive mucus production in the intestines, resulting in clear liquid stool. Additionally, dogs that eat something unusual—such as table scraps, spoiled food, or foreign objects—can develop digestive irritation.
Larger amounts of mucus in stool, associated with diarrhea, may be caused by certain intestinal infections. Bloody mucus in stool or mucus along with belly pain may signal a more serious condition, such as Crohn's disease, ulcerative colitis and even cancer.
Mucus – a jelly-like substance that's naturally found in the gut; white or yellow mucus may mean there's an infection, while a pink or red colour may indicate blood. Faeces (stools) – due to leaking from your bowel.
Blood in stool from cancer can appear as bright red streaks (from lower down in the colon/rectum) or dark, black, tarry stools (from higher up in the digestive tract), mixed with or coating the feces, often with other symptoms like thin stools, fatigue, or changes in bowel habits, but it can look like blood from many other causes, so seeing a doctor for diagnosis is crucial.
If your dog passes poo that looks like snot or slime, it is most likely mucus. Mucus can be mixed in with the poop or deposited on its surface. A little mucus is normal, and it lubricates the digestive tract. However, if your dog suddenly passes a lot of it, this indicates a medical issue.
There are lots of reasons why your dog's poo might be bloody. Like eating stuff that irritates the gut; bacterial, viral and protozoal infections; and medication side effects, to name a few. In many cases, it resolves on its own (with some bland food and time).
A little mucus in dog poop can be a sign of normal indigestion, while excessive amounts might indicate something more serious, such as stress, dietary sensitivities, bacterial or parasitic infections, inflammatory bowel disease (IBD), or colitis. Don't panic if you spot mucus in your dog's stool.
A single instance of mucus in otherwise normal stool may not be alarming if your dog seems healthy. Multiple slimy stools within 24 hours suggest an ongoing problem needing veterinary attention. Persistent mucus over several days, even without other symptoms, warrants a check-up.
Intestinal parasites (worms)
In many cases there are no symptoms of a worm infestation but if clinical signs do present, mucus in their poo could be one of them. Your vet will be able to recommend the best course of treatment after examining your dog.
What Is HGE in Dogs? HGE is a form of gastroenteritis — inflammation of the stomach and intestines — characterized by an abrupt onset of bloody diarrhea and vomiting. The diarrhea of dogs with HGE is often described as resembling raspberry jam or jelly.
Hematochezia in Dog's Stool
Bleeding in this area will encourage your vet to investigate a particular set of conditions such as parvovirus, hemorrhagic gastroenteritis, cancer, viral and bacterial infections, parasites, digestion of something inappropriate, sudden change in the pet's diet, rectal injury, or colitis.
Loose runny poo with jelly like blood: this may be colitis (inflammation of the lower part of the bowel) – it should resolve in a couple of days, but sometimes needs treatment. Contact your vet if your dog is unwell or the symptoms persist or worsen.
The clinical signs of parvovirus can vary but generally include severe vomiting and diarrhea. The diarrhea often has a powerful smell, may contain a lot of mucus, and may or may not contain blood. Additionally, affected dogs often exhibit a lack of appetite, marked listlessness and depression, and fever.
Why is my dog is pooping blood and mucus? Bright red blood (hematochezia) and mucus are often accompanied by diarrhea and typically are a symptom of a disease affecting the colon such as parasites, infections or related to diet.
In these cases, it is important to provide your pet with ample access to water to prevent dehydration. Just like when humans get an upset tummy, keeping food simple can help your pet feel better. You can boil white meat chicken and rice (NO SEASONINGS) and serve this to your pet instead of their normal dog food.
Yes – stress or anxiety can cause gastrointestinal upset, including bloody stool. Can worms cause blood in dog poop? Yes – intestinal parasites are a common cause, especially in puppies or dogs that haven't been wormed regularly.
It's normal to see some clear mucus in your stool. But a flood of mucus or mucus that looks bloody, off-white or yellowish is something you may want to discuss with a healthcare provider. It may be a sign of a digestive disorder or other condition that affects your digestive system.
Bright red blood in your stool might be more alarming because it suggests active bleeding. Darker blood usually suggests older bleeding that's not active anymore. But darker blood in your stool can be deceiving. It doesn't always mean the bleeding has stopped, only that it's coming from someplace higher up.
Ask a healthcare professional if you're concerned about your stool color. If your stool is bright red or black — which may indicate the presence of blood — seek medical attention right away.
If a polyp or tumor is low in your rectum, you could see bright red blood similar to what comes from hemorrhoids. Slowly bleeding tumors at the beginning of the colon, on the other hand, may cause dark red or black stools.
Blood isn't the only reason why poop can look reddish or black. Food and medications can affect poop color and texture. So if your poop doesn't seem right, take a minute to think about what you've been eating. Reddish stools can be caused by eating lots of beets, cranberries, red gelatin and tomato juice.
Blood clots in stool are a sign of bleeding somewhere in your gastrointestinal (GI) tract. Bright red blood in your stool usually signals bleeding from your lower colon or rectum, while dark red blood can indicate bleeding higher in the colon or small bowel.
