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 sign range from benign to untreatable, depending on the cause. 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 signs 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

Small amounts of 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 signs, 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 veterinary attention

Diarrhea

  • Diarrhea is 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 may be recommended 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 signs 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 recommend antidiarrheal mediations. 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 may require surgical 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 cause. Although some issues are mild enough not to warrant a return trip to the veterinarian, many other disorders will require an additional visit to check how the patient is responding to treatment.

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. 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.

Little Bit Of Reddish Mucus In Soft Stool

Hello! My 2 month old puppy just got his first set of shots yesterday and a heart worm tablet. Today I noticed his stools were softer and more wet looking but not diarrhea. Then the last 2 stool had a bit of mucus in them that was a little red. I smashed the stool to see if there was blood in it and it looks fine- no trace of red/blood in it from what I could see. He’s acting completely normal other than the mucus issue.

Hello Soft stool with mucus can be diet related or due to intestinal parasites (worms). I recommend monitoring him closely for the next 24 hours, and if he had soft stool again take him to get checked out by a veterinarian. Good luck.

Diarrhea
Incontinence Of Bowel

I just brought a 9 week old lab/sherpherd mix puppy home 2 weeks ago. For the first week she was crate trained and had no accidents. Last week we switched her dog food from Pedigree Puppy to a brand from Tractors Supply made specifically for lab puppies and since she has had accidents in her crate every night between 2:30-3am. So I started feeding her earlier in the day and having her last meal around 5pm...she still had poopy accidents in her crate. While I'm at work I leave her in the garage with access to some yard space...after about 10 hours she usually has 8-10 piles of bowel movements. Most are soft and mucous-like. I do feed her Nyla bone treats-Filet Mignon flavored and she loves them but could they be the cause? I also gave her worming medicine this past Sunday to see if perhaps she had worms but I haven't seen any in her feces. The mucous is real thick like-like a mucous plug. She shows no other symptoms...no fatigue, no bloating. She has scooted her butt on the ground a couple of times. Any suggestions?

My 8 month mini Aussie has been kind of slow these past couple days and is avoiding her food and water. She pees very little at a time and usually twice with in 3 minutes of the first. She's had diarrhea and solid stole but the solid was covered in mucus but no blood. Any suggestions would be great. Thank you!
