Why Is My Dog Pooping Yellow

Why Is My Dog Pooping Yellow? – What To Do Now!

Our carnivorous companions do not speak, it is often by observing the stool that we can diagnose a health problem in them. So should we be concerned about an unusual color in our pet’s diarrhea?

In general, the dog’s “normal” feces can be dark brown, light brown, sometimes beige, or even slightly yellowish, without being so. If the stools are well molded or very slightly soft, there is nothing to worry about.

But if the stools are yellow, or even orange or creamy, and they have been very soft or even watery for several days, weeks, or months, this means that your dog is certainly affected by Coccidiosis or that he ate food containing certain vegetables unsuitable for the diet of our domestic carnivores.

We will discover in the rest of the article how to stop yellow stools in dogs and especially understand why they happen.

Why is my dog pooping yellow?

There are two major reasons a dog develops loose yellow stools. On the one hand, Coccidiosis (microscopic parasitosis), and on the other hand, food made from certain vegetables or fruits that are unfortunately quite frequently found in commerce.


Today, it is estimated that around 10% of dogs suffer from Coccidiosis and up to 29% in some herds. What you should know is that Coccidiosis is very often the result of food unsuitable for the original carnivorous diet of our dogs, which inevitably causes a weakening of the intestinal immune defense. It is then the door open to the development of intestinal parasites such as Coccidia giving Coccidiosis.

In addition, these protozoa being invisible to the naked eye, it is then all the more difficult to detect them. This is why a visit to the veterinarian will be necessary to confirm the diagnosis.

Certain vegetable or fruit-based croquettes

Not all dogs with yellow, loose stools have Coccidiosis, however. Indeed, thanks to our retreat as breeders, we have regularly observed that these abnormal stools can come from a diet based on vegetables or fruits.

Whether they were grain-free or grain-based kibbles, the dogs we met with yellow and soft stools consumed foods made from vegetables or fruits, and in particular starchy vegetables, tubers, or legumes such as potatoes, sweet potatoes, chickpeas, peas, tomatoes, lentils… These vegetables are of course unsuited to the carnivorous diet of our dogs. Already difficult to digest in humans, they are the consequence of numerous loose stools and chronic diarrhea in our domestic carnivores.

Also note that some vegetables and fruits are already registered at the Animal Poison Center, such as potatoes or grapes. All the more reason to eliminate them from the bowls of our carnivorous companions.

We do not know what causes this reaction following the consumption of vegetables or fruits. However, we were able to observe that after a return to a diet low in cereals and without vegetables, a lot of dogs found in a few days normal stools (brown to light-dark, and well molded).

Why does Coccidiosis develop so much and affect around 10% of dogs today?

Many owners or breeders forget to use a food of sufficient quality or are not aware of using a diet unsuited to their Organic and Natural Needs, allowing the dog to protect itself naturally against parasitic attacks.

Because it is a fact: parasites develop even more when the immune system is weakened due to a diet not adapted to their natural diet. 

This shows that the quality of food is essential in the fight and prevention of this kind of parasitic disease.

At the start of our activity as breeders, we were not spared by this parasitosis (coccidiosis) which results in very soft and yellowish stools. But when we understood the influence of diet that was actually at the very root of these parasitic infections, by making the right choices, we never had a recurrence again and has been for almost 20 years now.

We will see at the end of this article how to make the right choices in your dog’s diet to avoid these chronic loose or even watery, yellowish stools.

How do I diagnose Coccidiosis in the presence of soft yellow stools in my dog?

Faced with symptoms reminiscent of Coccidiosis (ie loose or even liquid and yellowish stools that can even draw towards orange or beige), it is advisable to have recourse to your veterinarian. He will then carry out a specific screening to diagnose Coccidiosis, upstream of treatment. Request a complete parasite test, insisting on including the Coccidiosis test which often is not included in the general parasite test.

Note that many dogs (more than 10%) could be saved from being affected by this parasitic disease which leads to soft yellow stools, or even watery yellow diarrhea. Thus detected, Coccidiosis can be treated as it should, with the appropriate medication that we will discover in the next chapter.

How to treat Coccidiosis effectively?

Coccidiosis is a microscopic parasitic disease that is easily treated, provided certain precautions are taken with medication. To begin with, you should know that dewormers do not treat the entire parasitic spectrum (all parasites), far from it. But in the specific case of Coccidiosis, it is even more specific: indeed no dewormer is effective in the treatment of this infectious protozoan!

Thus, to effectively treat Coccidiosis, it will be necessary to use an antibiotic from the Sulfonamide / Timetoprimes family, such as the very specific drug Bactrim. The treatment with Bactrim should be given for 5 days and will allow the dog to regain its good health.

It is not uncommon to see a return of well-molded stools as early as 48 hours after the start of the treatment. But beware: before using an antibiotic such as Bactrim, the dog’s weight must always be taken into account to prescribe the correct dosage.

What food to choose to avoid yellowish watery stools and recurrence in my dog?

We have to be very vigilant about the quality of foods that are available on the market or in specialized stores. These croquettes are generally very rich in poor materials, in cereals, in vegetables, and/or contain animal by-products and/or plant by-products.

As we have seen, a dog is not made to digest vegetables or to ingest food that we humans would not eat.

As we see through the countless consumer feedback that we have collected in recent years, vegetables are often the cause of chronic diarrhea, sometimes with yellow stools and strong irritation of the intestinal flora. It is extremely important to remove vegetables and fruits from your pet’s bowl now.
