Common Causes of Puppy Diarrhea

Puppy diarrhea can be triggered by various factors, often linked to their instinctual emerging curiosity and still immature, developing immune systems. Like many young mammals, puppies explore the world by tasting and chewing on interesting or new objects they find in their busy explorations. This behavior can lead them to ingest non-food items like grass, sticks, or even feces of various animals including their own, which may result in gastrointestinal upset and diarrhea. Additionally, parasites such as worms or infections from bacteria or viruses can be culprits of diarrhea in puppies. Stress, sudden or gradual dietary or water changes can also disrupt their digestive health. Growing puppies can find themselves off balance due to many varying factors, and they will be especially sensitive during and in the weeks after weaning.

Post Weaning Diarrhea

At Painted Blue Aussies, we place a high priority on the health and well-being of our Australian Shepherd puppies and Mini American Shepherd / Mini Aussie puppies. We take proactive measures by regularly treating them for a broad spectrum of common parasites and maintaining quarantine practices for unvaccinated puppies to safeguard against viral infections. Despite our best efforts, we acknowledge that diarrhea can and does still occur. The weaning process of transitioning from milk to solid foods is an especially sensitive time for our little ones, and that transition can produce symptoms off and on in our experience, for two weeks and sometimes up to six weeks.

Through experience and research, I've come to understand that weaning diarrhea is a natural, common, and unfortunately inevitable occurrence in puppy development, as well as in many other mammals and livestock. When we encounter diarrhea during or after weaning in our puppies, our priority is to provide gentle support and care to help them navigate through this digestive upset. Despite our best efforts, puppies may experience varying degrees of severity, ranging from soft stools to watery diarrhea, which can occasionally include traces of blood due to gastrointestinal irritation. This can be a normal part of the changeover of gastrointestinal flora and irritation as new bacteria settle in to aid in the digestive process of solid foods.

Recommendations For Managing Diarrhea

It can be frustrating when our Australian Shepherd puppies or Mini Australian Shepherd puppies / Mini American Shepherd puppies don't seem to be feeling their best. One of the most important things we've learned when dealing with transitional diarrhea is the value of time and allowing the nature of the body to work for itself. As long as they are eating, drinking, and playing happily, they often just need time for their systems to adjust and find equilibrium.

While we can recommend a few products to provide gentle support for their digestive systems during this process of establishing equilibrium, it's important to remember that these interventions can sometimes have unintended consequences and may even cause loose stools themselves. However, when used appropriately and in moderation, they should not cause harm and may offer some relief. The products listed below are products we occasionally use for puppies who find themselves out of balance.


Recommended Products

    – a lifesaving rehydration remedy that proves invaluable whenever your beloved dog or puppy faces stress or illness. With a decade of personal use for my own dogs, I wholeheartedly endorse ALWAYS keeping this formula on hand. This formula is great for helping keep puppies hydrated and energetic.

  • Firm Up! Pumpkin

    — is an excellent alternative to wet canned pumpkin. While canned pumpkin is beneficial, it can often grow mold quickly when stored in the fridge. To avoid the extra hassle of freezing canned pumpkin in smaller portions, we recommend using this dried pumpkin product. Please follow the instructions provided on the package for dosage.

  • Bernie's Perfect Poop for Dogs

Occasionally, if a puppy's diarrhea does not improve over time, we may recommend a diet change. Sometimes, a particular food may not agree with a puppy, and switching to a different diet can help resolve the issue.

However, we advise against using veterinary prescription diets for this purpose. While these formulas may show short-term improvements, we have observed that they can lead to more significant problems in the long run, such as a recurrence of diarrhea, skin issues, coat problems, and even ear infections. Instead, we advocate for selecting high-quality, balanced commercial diets that are suitable for growing puppies to promote overall health and well-being.

Please feel free to reach out with any questions or concerns you have about managing diarrhea in your Painted Blue puppy during their transition to your home. We are here to provide guidance and support to help you and your puppy navigate this period effectively. Your puppy's well-being is our priority, and we're committed to assisting you every step of the way!
