What is Mucus in the Stool?

Some mucus is normal and necessary in order to facilitate the movement of the waste through the bowels. When the amount of this mucus increases in volume or changes color or smell this could signal a problem developing for your dog. The underlying issues that can cause this symptom range from the benign to the untreatable. Because some of the causes of mucus in stool can be time sensitive it's best to contact your veterinarian as soon a possible, especially if the dog has other symptoms such as diarrhea or fever.

Most stool includes some mucus to facilitate its movement through the bowels. Increases or changes in the mucus composition of your dog’s stool may be indicative of underlying conditions.

Symptoms of Mucus in the Stool in Dogs

Mucus within the stool generally isn’t a problem by itself. If it is much larger amounts than you normally see or if paired with the following symptoms, a call to the veterinarian is warranted and a stool sample should be gathered.

  • Abdominal pain
  • Accompanied by diarrhea
  • Fever
  • Lethargy
  • Only mucus is being expelled
  • Refusal to eat or drink
  • The mucus has a color
  • There is a change in color in the stools
  • Vomiting

Types

 

There are changes to the feces that may occur concurrently.

Black and tarry

  • This color and texture are generally caused by blood from the stomach or upper intestine
  • If you see this kind of stool, collect it and call your veterinarian as soon as possible

Blood in stool (red)

  • This is fresh blood in the stool which may indicate bleeding in the lower intestines
  • Collect a sample and seek emergency medical attention

Diarrhea

  • Diarrhea is most often caused by a viral or bacterial infection, but there are other triggers
  • Dogs with diarrhea are at high risk for dehydration and should be monitored closely
  • If blood clots are also seen the situation should be treated as urgent 

Grey and greasy looking

  • Usually caused by too much fat in the food 

Worms

  • Worms in the stool are parasites
  • Contact your veterinarian as soon as possible for prompt diagnosis and treatment

Diagnosis of Mucus in the Stool in Dogs

In order to make a diagnosis your veterinarian will want a full history of the animal, as well as a general physical exam. Questions regarding your dog’s diet and appetite will be asked, as well as inquiries about whether any vomiting or diarrhea has been recently observed. A biochemistry profile, complete blood count, and urinalysis will be ordered to determine the underlying cause. A colonoscopy and a fecal float may also be recommended. The fecal float test can help your veterinarian to determine if adult parasites are present in the canine’s system and the colonoscopy allows a visual inspection of the large intestine to detect tears or other inconsistencies. If a definitive diagnosis has not been determined by this point, additional tests will depend on symptoms and on the results of previous tests. If foreign objects or tumors are suspected x-ray and ultrasound imaging may be used to try and detect them.

Treatment of Mucus in the Stool in Dogs

Treatment of mucus in the stool will depend on the underlying cause. As the causes of increased mucus in the stool can cover a large range of underlying causes, the treatments are also many. In cases of indiscriminate eating or stress, it may clear up with no further treatment. A short term change to bland, easily digestible foods may be a beneficial change, and in some mild cases your veterinarian may even recommend Imodium to counteract an upset stomach. If your pet has a viral, bacterial, parasitic or fungal infection, the proper medication to clear up the disease will be prescribed, and if food allergies or sensitivities are diagnosed then a hypoallergenic diet may be recommended. Probiotics may also be recommended to help the patient recover, especially after antibiotic or antifungal treatments. If a tumor or another growth is involved, it is likely to require excision which may be followed by chemotherapy.

Recovery of Mucus in the Stool in Dogs

Depending on the underlying cause, recovery and management methods can be extremely variable. You will need to make sure that you make any changes to your dog’s diet or environment as recommended by your veterinarian, and if your pet was prescribed any medication it is imperative that you give them the entire course to prevent reoccurrence of the problem. The dietary and lifestyle changes for some patients may be short-term or life-long dependent on the symptom’s cause. Although some issues are mild enough not to warrant a return trip to the veterinarian, many other disorders that can result in additional mucus will require an additional visit to check how the patient is responding to treatment.

Thank you for your question. She may be having diarrhea due to the food change, or she may have parasites, as those are very common in puppies. Grain-free dog foods are not recommended, as they can lead to heart disease in dogs. It would be best to try a good quality puppy food, Hill's and Royal Canin are two brands that maintain high quality standards. If the diarrhea is not improving, having your veterinarian look at a stool sample for parasites would be a good idea.

Diarrhea And Now Lethargy

diarrhea happened earlier then she had an accident in her crate, which she DOESN'T do. It wasn't diarrhea tho but wasn't really hard, just big and had a little bit of mucus in it. She's very tiny for her breed, about 4-5 lbs. Now she is just acting tired and not like herself. All this happened from last night to tonight.

Thank you for your question. This problem maybe caused by many things, but if she is not vomiting, eating normally, and generally doing okay other than the stool, you can try feeding her a bland diet of boiled white chicken and boiled white rice for a day or two and see if that helps with her stools. If she continues to have the mucus in her stools or is lethargic, then it would be best to have her seen by a veterinarian as there may be more going on. I hope that all goes well for her and she feels better soon.

Diarrhea

My dog is teething at the moment and her apatite has become non existent with her chow. She is still eating jerky and treats but no food. The last two days she started to have diarrhea and now she is pooping mucus with a little fresh blood between her poop. She is still drinking plenty of fluids and her general attitude has not changed but obviously she doesn't have as much energy since she isn't really eating anything substantial. Is it just teething or is it more serious because of the blood?

Thank you for your question. Blood in her stool and a loss of appetite are not normal signs of teething, and I am concerned that there may be more going on. It would be best to have your veterinarian examine her and see what is causing the diarrhea, blood and loss of appetite. I hope that all goes well for her and she feels better soon!

Thank you for your question. I'm sorry for the delay in answering, this platform is not set up for urgent responses. Puppies can have problems with parasites, infectious diseases, or eating things that they shouldn't. If he is still having problems, it would be a good idea to have him seen by your veterinarian, as they can see what might be going on, and get treatment for him.

Thank you for your question. I apologize for the delay, this venue is not set up for urgent emails. Puppies very commonly have parasites, and that stool that you describe is not totally normal. It would be best to have your pet seen by a veterinarian, as they can examine them, see what might be going on, and get any testing or treatment taken care of that might be needed.

My puppy Sam 5months corgi/mini aussie mix. His poop was brown, formed & soft one day. He would ask to go outside and has not had an accident inside the home for 3 months. One day he was incontinent of urine & his poop was green diarrhea mucus looking; he would void & poop at least once every hour. (4 days now) Appetite & thirst went unchanged, we did not change his food diet. Energy, playfulness has remained the same. Not lethargic. Anyone have any ideas?

Loose Stool
Mucus In Stool
Frequent Stool

My 4 yr old miniature poodle has had loose stools on and off for years with no identified reason. The past month she has had a lot of mucus and loose stool. She has no other symptoms otherwise, healthy and active. She has always had digestive issues on and off, vomits a few times a month for no reason (but she gulps her food and a greedy eater)She also scratches and licks a lot. I suspect allergies, but have tried isolating different ingredients and can't identify anything in particular. Then for weeks she will have normal stool confusing it even further. She does not have access to eating foreign things as she is in the house or under observation on walks. A few months ago I slowly introduced a different kibble to remove her off high lentil/pea kibble. First I tried Nutrisource and slowly switched to Fromm Gold for adult dogs which she has been on for a couple of weeks. I give her 1/3c kibble in the morning, and for years I have mixed 1/3 can Wellness Core Healthy Cuts with her kibble at evening meal. (I have to be careful about giving her canned that has too much fat) Even though he diet is stable - same thing every day (plus 3 small puppy biscuits) she still has mucus in her stool and frequent bowel movements. No vomiting, not lethargy, no stretching etc I have given her Proviable probiotic in the past for loose stool so am starting her on it again. Pumpkin does not help. (I might add I have an 8 year old mini on the same food, and she is having no problem

Our 10 year old Lhasa Apso/Poodle mix Princess has been having a lot of trouble with bloating, mucous in her stool, lethargy, vomiting bile and a severe increase in thirst. She has got to the point to where she will get excited about something for about 2 minutes and then is down for the rest of the day with very little energy to pick herself up. I have had multiple tests run and everything they have checked has come out ok (liver, kidneys, blood sugar,exc.) I dont know what else to do but i cant stand to watch her suffer like this.
