Yellow Dog Poop — Why Is My Dog Passing Yellow Stools?
Yellow stools and dogs
A pet parent’s role can often be a thankless one — think about how much time we must spend, over the course of a dog’s lifetime, picking up poop, for example. It’s unlikely that anyone’s actually calculated the time we devote to that task but it’s probably hours and hours.

The bottom line is that we get to see a lot of our dogs’ poop. So much so that we can very quickly notice if the poop looks unusual, whether that be diarrhea or a different color. A dog’s stool can vary in color. This can be quite normal but in some instances can be a warning sign that something isn’t right.

If your dog is passing black stools or tarry stools (which may have blood in them), there could be a health problem.

But what of yellow dog poop? If a dog's poop is yellow, what does that mean? Is it something to worry about?
My dog’s poop is yellow — why?
If you’re witnessing yellow dog poop, there could be a number of causes. A one-off incident is probably nothing to be concerned about but regular or repeated changes in the color of your dog’s stools could be an indication of anything from a mild stomach upset to a serious gastrointestinal condition.

Causes of yellow dog poop may include:

Consumption of non-food items
Consumption of non-food items can cause your dog to have yellow diarrhea. Dogs can have a habit of eating whatever comes their way without thinking — this can include pieces of trees, grasses, rocks, or even household items, like socks. 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
Gastroenteritis 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, loss 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, so your dog will need veterinary attention. 
Irritable bowel syndrome (IBS)
If you detect mucus-yellow dog poop, it could be evidence of Irritable bowel syndrome (IBS). IBS 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’s poop is yellow
If your dog’s poop is yellow, with diarrhea or a mucus substance, first things first – don’t panic. It could all be completely normal; bouts of periodic diarrhea and stool changes can cycle in and out of your dog’s life, lasting only one or two bowel movements.

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 that 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 vet is in the best position to diagnose this, and make a treatment plan.

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 the vet 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.

Preventing yellow dog poop
Is there anything a pet parent can do to prevent yellow dog poop from affecting their pup? While that’s always going to be difficult to achieve, there are steps you can take to help reduce the risk as much as possible.
So, how can you try to prevent your dog from having yellow diarrhea? Close monitoring of your pet’s 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.

A fatty diet can lead to issues such as pancreatitis. If your dog has this condition, you should consider a permanent switch to a type of dog food that’s been specially formulated to help aid digestion. You can read our recommendations for the best food for dogs with pancreatitis here.
Careful monitoring of your pet’s home environment and those areas where he or she 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.

If your dog’s poop is yellow because of a medical condition, the resulting treatment can be expensive. Pet insurance can help to cover some of the costs that may arise. If you don’t already have a policy, start searching for cover today. Compare the best pet insurance plans in seconds using Wag! Compare.

My pet has the following symptoms:
Yellow Poop
We boarded our dog for the weekend last week and since coming home his poops have not been normal. The first night he had completely diarrhea every 2 hours, I gave him some anti-diarrheal and he didn’t go again for another 2 days. The poops have gotten better, not completely liquid, but not as solid as normal, and have been yellow tinted as well. He seems normal, no lethargy, no abdominal pain, eating and drinking normally, it’s just his poops every since coming back home.

Thank you for your question. He may be having a case of stress colitis, from boarding, or he may have eaten something that you're not aware of. He may also have picked up a parasite. You can try feeding him a bland diet of boiled white chicken and boiled white rice for 2 to 3 days, and see if that helps things. If things resolve then you should be fine. If the diarrhea or the strange coloration to his stool is continuing, then it would be best to have him seen by a veterinarian. They will be able to examine him if needed, and get any medication that he might need. I hope that all goes well for him.

Hello, So sorry to hear about your dog. We worry about parasites with the yellow stool. It would be best to see your vet. They can check a fecal sample and start your dog on medication to help with these parasites. I hope your dog starts to feel better soon.

My pet has the following symptoms:
Diarrhea
My two months old gsd don't want to eat anything but drinks a lot of water. His poop is very liquid with yellowish color. I consulted my vet and she says it is just normal infection. Please help me to find what my puppy is going through.

I don't think that there's such a thing as a normal infection in a 2 month old dog. Your puppy may have parasites, form an infectious disease. If he is not currently on any medication, I might ask for a second opinion so that he can get treatment. I hope that he is okay.

My pet has the following symptoms:
Diarrhea
Yellow Skin
Yellow Gums
Yellow Grainy Slimy Stool
We have a 5 year old Lhasa Apso called Billy. He is fed semi moist food with a portion of boiled beef heart daily. His morning poop is usually of normal form/semi firm consistency but his afternoon poop can be yellow, grainy and slimy. This is not every day most occurs at least 3 times a week. He has always seemed like a lazy dog and seems to sleep a lot throughout the day. I am worried about the yellow poop. My other Lhasa eats the same diet and does not have this problem.

If Billy has yellow gums, yellow skin, and yellow stool, he needs to be seen right away by a veterinarian. He may be having liver problems from what you are describing, and may need treatment.
