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, Dry, And Crumbly Poop
Yesterday my dog ate more of an elk antler than I noticed. She had healthy BMs yesterday but this morning she had a hard, dry, yellow and crumbly BM. She’s had 3 of those today. However, she’s not straining, not in pain. She’s active and acting normal and drinking and eating normally. Should I wait to see if today is just an off day and if things go back to normal? Should I be concerned about an obstruction?

Hello, If she is having a BM then she is not obstructed. Most dogs that are obstructed are also vomiting. She may be just having an off day. If she is not back to 100% tomorrow, it would be best for her to see your vet.

My pet has the following symptoms:
Dark Underbelly, Yellow Feces, Lethargic, Shivering
Yesterday I noticed a strange coloring on his belly, right where his penis is. He didn’t eat at all yesterday. He had maybe a handful of small treats. He’s urinating fine. When he pooped, it was mushy and yellow. Last night when it was time for bed, he was restless. He couldn’t get comfortable. Kept jumping off the bed and turning in circles barely taking his butt off the floor.

Hello- Thank you for your question. It sounds like he is pretty uncomfortable based on the symptoms that you are describing. Without examining him it’s really hard to tell exactly what is going on as I can’t see the skin near his prepuce. That, coupled with his inability to get comfortable and the yellow stools warrants a veterinary visit today. They will be able to examine him and perform diagnostics to assess what is going on. They will then be able to provide an appropriate treatment plan to get him feeling better. I hope he feels better soon.

Hello, thank you for your question. I am sorry to hear that your dog is having diarrhea! Without examining your dog, it's very difficult to know what might be going on. Diarrhea can be caused by anything from intestinal parasites, to liver disease, to issues with the pancreas, to just intestinal upset from eating a new food or treat. I recommend contacting your veterinarian and letting them know what is going on - they may recommend a stool check to rule out microscopic intestinal parasites such as giardia, as this is often associated with yellow, loose stools. Please wash your hands thoroughly after handling any fecal material from your dog in order to be safe. I hope that your dog starts feeling better soon! Have a great weekend!

Thank you for your question. That diarrhea that you're describing maybe from parasites, dietary indiscretion if he ate something he wasn't supposed to, or an intestinal infection. If it continues, it would probably be best to have him seen by your veterinarian, as they can assess his health, see what might be causing this, and get treatment for him. I hope that all goes well.

My pet has the following symptoms:
Diarrhea With Mucus
Hello, My Doberman puppy has been having diarrhea since yesterday (7.21.20) and throughout the night. Almost every few hours. It is a yellow color with mucus in it. There are no worms or blood that I can see. There has been no change to his food. He is still eating, drinking and behaving normally. The only change is that I gave him a bone on Saturday (7.18.20) which he's been eating periodically. I have since taken away the bone. What should I do or when should I take him to a vet if his diarrhea continues?

Thank you for your question. If he is not vomiting, has a normal appetite, and seems okay otherwise, you can try feeding him a bland diet mixture of boiled white chicken and boiled white rice for 2 to 3 days. You can also add a probiotic to his food, Forti Flora is one that you can get over the counter. If that does not help, and he continues to have diarrhea, or he starts vomiting, or not wanting to eat, then it would be a good idea to have him seen by your veterinarian. I hope that all goes well for him!

My pet has the following symptoms:
Weight Loss
Decreased Appetite
Yellow Vomit
Yellow Soft Stool
Undigested Food In Stool
For the past month and a half my dog has been sick and they haven't been able to figure out exactly what's wrong with her they put her on anti vomit medication and anti-diarrhea medication and that helped a little but then her stool started turning yellow and soft you can also see the undigested food in her stool. She's now vomiting yellow what looks to be the same has her stool. She is lost her appetite and doesn't even want to eat anything. I've been going to the vet every couple of days to try and see if there's something else that can be. But I I'm out of money and I really don't want to see my puppy die, I'm not sure what else to do.

My pet has the following symptoms:
Poor Stool Control
My 2 Year old Border Collie Mix is passing yellow stool. I have changed the dog food to Pedigree recently because my other dog started having seizures after we tried another type of dog food that seemed to have more health benefits. My other dog is fine, but my 2 year old is passing that stool though her behavior seems normal.
