When a puppy is born, all the vital signs can be monitored, including the color of its poop.
While it’s normal for newborn puppies to have yellowish or grayish stools during their first few weeks of life, it’s important to pay attention to any changes in color and consistency.
If your pup’s poop has turned yellow and you’re not sure what to do, here is some information you need to know.

What does yellow poop in newborn puppies mean?
Newborn puppies are typically born with yellow poop that may contain mucus or bits of undigested milk from their mother’s milk.
This type of stool is considered normal for the first several weeks of life and should not be cause for concern.
However, if the yellow poop persists beyond three weeks or if it takes on a greenish hue, this could indicate an underlying medical condition, such as an infection or digestive disorder, that requires veterinary attention.
Another reason why a puppy might have yellow poop could be due to issues with nutrition.
If your pup isn’t getting enough nutrients from its mother’s milk or from formula feeding, this could lead to yellow stools as well as other signs of malnutrition such as poor growth and poor coat quality.
If you suspect that this might be the case, contact your vet right away for a proper diagnosis and treatment options.
When should you worry about yellow poop in newborn puppies?
While occasional bouts of the yellow stool are usually nothing to worry about in newborn puppies, there are certain cases where prompt medical attention is necessary:
- If your pup’s stools become increasingly watery or contain blood or mucus,
- If they develop diarrhea
- If they show signs of lethargy or appear unwell,
- If they seem dehydrated (check by pinching their skin),
- If they pass more than six stools per day (for newborn pups),
These are all potential indicators that something more serious might be going on and warrant further investigation by a vet.
It’s always better to err on the side of caution when dealing with health issues in young animals, so don’t hesitate to seek professional help if you’re at all concerned about your pup’s wellbeing.
Is it normal for newborn puppies to poop yellow?
It’s perfectly normal for newborn puppies to have yellow-colored poop. This is because the puppy’s diet consists mainly of its mother’s milk, which contains yellow-colored fat.
When a puppy eats its mother’s milk, the fat passes through the intestines and is eliminated as yellow-colored feces. Yellow-colored poop in puppies can also be caused by an imbalance of bacterial flora in their digestive system or an infection of some kind.
If you notice that your puppy’s poop is consistently yellow or if it has any other strange color or consistency, it’s important to take them to a veterinarian as soon as possible for a checkup and diagnosis.
It’s also important to make sure your puppy is getting enough nutrition and hydration. If you think they may not be getting enough nutrients from their mother’s milk, you can supplement their diet with commercial puppy food or wet foods appropriate for their age and breed size.
Make sure you consult with your vet before making any dietary changes to ensure they are getting all the necessary nutrition they need as they grow up healthy and strong!
How can yellow poop in newborn puppies be treated?
In most cases, treating mild episodes of yellow stools will simply involve making sure your puppy gets enough nutrition and fluids, either through breastfeeding or formula feeding (if needed).
Your vet may also recommend adding probiotics to their diet, which can help improve digestion and restore balance within their digestive system.
In more severe cases where an infection is present, antibiotics may also be prescribed by your vet, depending on the situation.
For any other underlying conditions such as digestive disorders, special diets may need to be implemented for proper management, so it’s best to get professional advice from a qualified veterinarian before proceeding with any home remedies or treatment plans.
The bottom line
It’s important for pet owners to keep a close eye on their puppy’s health, especially during those first few weeks after birth, as even small changes can indicate something more serious going on internally, which can go unnoticed until it’s too late without early intervention.
If you notice anything unusual, such as persistent episodes of off-color poops in your dog, don’t hesitate to seek help right away!
