What are Passing Yellow Stools?

When your dog is passing yellow stool, it means that his feces are yellow in color instead of the normal brown color.  Any changes in the normal color of your dog’s stools which are noted should be watched carefully.  There are several reasons why this could be happening:

  • Consumption of non-food items 
  • Gastroenteritis
  • Liver problems
  • Gallbladder problems
  • Pancreas problems
  • Intestinal infections
  • Irritable bowel syndrome
  • Food allergies

Why Passing Yellow Stools Occurs in Dogs

There are a number of reasons why yellow stool occurs in your canine companion and some of them are more serious than others:

Consumption of Non-food Items

This can include pieces of trees, grasses or even household items. Foreign body consumption can include virtually anything which isn’t food and isn’t supposed to be eaten. These items may not be digested by your pet’s system.

Gastroenteritis

This is inflammation of the intestinal system, generally this includes the stomach and intestines.  The causes of gastroenteritis can include infections from bacteria, viruses, parasites or reactions to new foods or medications.

Liver Problems

Liver problems cause jaundice (icterus) which will discolor the eyes, skin, urine and feces of your pet. Damages to the liver can occur from many diseases, toxins, drugs, cancer and inflammation of the liver caused by bacterial and fungal infections.

Pancreatitis

This is inflammation of the pancreas which occurs as a result of digestive enzymes leaking into the pancreatic tissue.  Abdominal pain, depression, lack of appetite along with vomiting and diarrhea can occur in some dogs.  Chronic pancreatitis can sometimes lead to diabetes in your pet.

Gallbladder Problems

This condition occurs when there is a stoppage of bile flowing from the gallbladder to the intestines.  This can occur due to trauma to the gallbladder, or from an obstruction like a gallstone, congealed bile or tumor of the gallbladder and can turn the eyes, skin, urine and feces a yellow color.

Intestinal Infections

These can include bacterial, viral, fungal and parasitic infections.  If left untreated, any of these can progress to more serious conditions in your pet. 

Irritable Bowel Syndrome

This can cause a yellow mucus to be present in your dog’s stool.  This condition needs to be treated as early as possible to prevent progression into a more serious health condition for your pet.

What to do if your Dog is Passing Yellow Stools

Bouts of periodic diarrhea and stool changes can cycle in and out of your dog’s life, lasting only one or two bowel movements.  This can be normal for some situations with your dog, unless his condition begins to deteriorate.  However, if the yellow stools continue to be passed beyond a day or two, or if your dogs' condition is deteriorating, you should call your veterinary professional for medical evaluation.  The condition which may be at the root of the yellow stool may be relatively minor or it can be a major health condition which will need to be treated urgently.  

Your veterinarian will examine your pet and perform any needed testing to determine the cause of the yellow stool.  In many cases, this diagnosis proves to be a “ruling out” situation as he eliminates the many possibilities for the yellow stool in your pet.  Your veterinarian will treat the underlying cause with medications, surgical procedures, dietary supplements or dietary regimen changes as needed based upon his findings and diagnosis.

Prevention of Passing Yellow Stools

For many of the possible reasons for the passing of yellow stool by your pet, close monitoring of his lifestyle is the best measure of prevention. For conditions like pancreatitis, liver and gallbladder problems, dietary regimens will need to be evaluated to ensure that your pet is getting a balanced diet without excess fats and carbohydrates which may not be easily digested. 

Careful monitoring of your pets home environment and those areas where he exercises and plays is also a good idea, eliminating as many of the potential non-food items which might interest him enough to ingest them.  

Keeping up with regular checkups, vaccinations, and parasite control will help to reduce the opportunity for parasitic infection to take root in your pet’s intestinal tract.

Examinations done at home on a regular basis can also help to identify painful areas on your pet which could relate to internal problems which need attention.  This can be incorporated into the normal time you spend with your pet in play and attention giving.

Cost of Passing Yellow Stools

There are costs involved in keeping your pet safe and healthy.  Here are some of the costs involved with treatment of some of the causes of yellow stools in your pet:

  • Irritable bowel syndrome treatment costs can range from $500 to $3,000
  • For the treatment of chronic liver inflammation, the costs can range from $1,000 to $10,000
  • If your pet is suffering from pancreatitis, those treatment costs could range from  $800 to $6,000

Hi there, you are through to Dr Linda. One episode of slight diarrhoea is not necessarily a concern if your dog is otherwise well. Feed a bland diet of chicken and rice for 24 hours, offer a probiotic anti diarrhoea paste and ensure your dog is up to date with a good quality wormer. If the issue persists, we should have a vet check and possibly a faecal exam.

Thank you for your question. If the bland diet is not improving things, it would be a good idea to have her seen by your veterinarian. Possible causes may be parasites, or if she ate something that she wasn't supposed to - that can cause GI upset. I would not think that it would be related to the surgery if it is just happening now, but any time diarrhea doesn't respond to a bland diet for 2-3 days, then it is time to figure out why it is happening. I hope that all goes well for her!

Thank you for your question. Parasites are very common in puppies, and if the diarrhea has not cleared up with the bland diet that you have been giving, 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 treatment.

Yellow Poop

I have noticed my dog passing yellow stools and I thought it might be a food intolerance. I put her on rice and chicken but seems to have gotten better for a day and back to yellow poop today. While before the yellow was only in part of her poop today it was a mustard uniform colour. What shall I do?

Soft Stool

My male Maltese 2yo started with diarrhea and was put ontyljosin which helped. The vet switched him to several digestive appropriate foods but he won’t eat them. He has gone four days without eating. I have tried the vet recommended treat and he literally turns his head up. All his fecal tests are normal. The dr thinks he could be allergic to chicken so we switched to 93% fat free beef mixed in the dog food. He picks out the beef and leaves the dog food. Also he was perfectly trained on wee wee pads and now only goes to urinate. I think the soft stool doesn’t let him know in time although after he looks guilty

Solid But Bright Yellow Stool

My 10 year old spaniel mix with liver & disc disease & occasional seizures managed to find & eat a couple peanuts on Friday. She vomited twice & had the runs. Took a stool sample to the vets, which came back ok. Vet said to stop probiotic & supplements for 24 hrs. After such time I gave again & she had a normal, solid poop yesterday morning. Then extremely loose & watery stools twice in the afternoon. Did not feed her dinner (to let her tummy rest) vet again said no probiotic or supplements now for 48 hrs. She ate with gusto this morning & just now had a solid but bright yellow stool. I am extremely worried. Her vet office is closed today but I emailed a picture of her stool. Any advice or suggestions on what is happening in the meantime?

Diarrhea, Yellow Stool

My one year old Maltese suddenly started having loose stools that are the color of mustard now. We went on a camping trip and when we got back he threw up and it looked foamy, hasn't threw up since but began having diarrhea. Yesterday I made some rive and boiled chicken for him and that made the poop color normal but the consistency was still soft. He doesn't have bowel movements as often as he used to since eating the rice and chicken. He still drinks water, peeing well, gums are pink, skin retracts to normal nicely, he was playing today. He is in perfect health, never had problems so i am wondering if he ate something i didn't see when we were at camp or if he was just super stressed and that's what is causing it. If someone has any information i would really appreciate it
