Why Does My Puppy’s Poop Look Yellow?

There are several reasons why a puppy’s poop is coming out yellow. If the newborn puppy is pooping yellow during its first month, it typically isn’t a reason to be concerned. This is because, during their first month, the puppy’s diet consists of only milk. A milk-only diet does cause the newborn puppy to have very soft poops that have a yellow color to them. 

For this reason, during the puppy’s first month, seeing yellow poop is considered normal. During this time, the dog owners should still attempt to monitor the poop’s consistency to ensure it’s healthy. A yellow viscous bowel movement is normal, but if it becomes runny or watery, this is when the dog owners need to be concerned that something could be wrong with the pup’s health.

The puppy digests the milk over a period of a few hours. When they do release their bowels, the mother typically cleans the puppy up before the dog owner notices they had a bowel movement. This is why many dog owners aren’t aware that it’s normal for puppies to have yellow feces during their first month. There are only rare cases where the mother doesn’t clean it up.

Can Yellow Poop From a Puppy Be Bad?

After 4 weeks of age, a puppy can begin eating solid food, so it is no longer normal to see yellow poop. If the puppy begins having yellow poops while consuming a diet with solid food can point to several different problems. This could be anything from digesting food too quickly to a chronic disease, so you should make an appointment with the vet.

The most common reason a puppy has yellow poop after four weeks is an upset stomach. Their stomach may be passing the food through too quickly, which results in the odd coloring of the feces and diarrhea. Often, this has to do with the food they are being fed, as there could be an ingredient that they are allergic to or just doesn’t agree with their stomach.

Yellow poop in puppies is commonly a sign of a sensitive digestive system, which appears in many dog breeds. However, sometimes the problem is more severe, as yellow poop can also be a sign of a chronic disease or viral infection. Since a puppy’s health is not a guessing game, it’s important to contact the vet about their yellow poop.

How Do You Fix Yellow Puppy Poop?

When you notice your puppy has yellow poop and it’s past the age of 4 weeks, then you need to contact the vet. The vet will do a full exam on the puppy to look for any signs of stomach or gallbladder problems. If there is a more serious issue with the puppy’s health, the vet will know how to treat them properly. 

Since many puppies experience yellow poop due to digestion problems, it’s important that you feed them quality food with good ingredients from the start. Breeders advise against experimenting with different types of puppy food, so before putting them on a solid food diet, always research what ingredients are used in different brands to find the best quality food. This will help you eliminate brands that are full of fillers.

If you have been feeding the puppy different types of food, it’s recommended to speak with the vet about your next steps. Your vet may recommend using a probiotic or a digestive support supplement. Some of the top choices for supplements include Purina Fortiflora Canine Nutritional Supplement Box, and Zesty Paws Probiotic Bites with Natural Digestive Enzymes Chews. These supplements provide the nutrients the puppy needs to maintain a healthy digestive system.

Final Thoughts- Newborn Puppy Poop Yellow

Since newborn puppies are more susceptible to infections and illnesses, it’s important that you monitor their health. One problem that sometimes occurs in puppies is yellow poop. If the puppy is in its first month of life, yellow poop is normal because they are on an all-milk diet. They are not consuming any solid foods at this point and digesting the milk very quickly, which turns the poop yellow.

If you notice yellow poop after four weeks of age, always contact the vet for assistance. Some of the common reasons this happens are sensitivity or allergies to food, digesting food too quickly, infection, or chronic illness. While changing the puppy’s food is important, it can also be risky to experiment with too many foods while the puppy is still young.

Change in stools can often point to a health problem with puppies. This is why it’s recommended to consult with a vet when you notice changes to your puppy’s poop. Whether it’s a change in color or consistency, there is always a reason for it. Since the puppies are so small, changes in their feces should not go ignored.
