What Happens If A Dog Eats Too Many Probiotics?

Are you concerned you’ve given your dog too many probiotics?

Maybe its the first time you’ve offered this supplement, maybe you’ve suddenly realized that you could have been giving too much.

Either way, I’m here to help.

Today, I am going to be breaking down what is likely to happen if a dog has consumed more probiotic than the recommended dosage.

Try not to panic. Stay calm, and keep reading.

Rest assured, this guide will address all your worries, providing the reassurance and guidance you likely need.

So without further ado, let’s get started.

What Happens If A Dog Eats Too Many Probiotics?

If a dog eats too many probiotics, they may experience digestive disturbances like diarrhea, gas, and bloating. Overconsumption can also affect appetite.

If a dog ingests an excessive amount of probiotics, several adverse reactions can manifest.

The primary reactions are digestive disturbances.


Diarrhea, for instance, occurs because the sudden influx of bacteria can offset the delicate balance in a dog’s intestines.

This can lead to increased water content in the stool, making it loose and frequent.

Gas & Bloating

Similarly, gas and bloating may arise due to an overactive fermentation process in the gut, fueled by the excess bacteria.

Changes In Appetite

Changes in appetite are another concern.

When a dog’s digestive system is upset, it may not feel like eating, potentially leading to weight loss or other related issues.

This is a natural response, as the body may be trying to prevent further ingestion of substances causing the imbalance.


Some dogs also develop constipation as they adapt to the altering gut flora.

Rare Side Effects

In extreme scenarios, while rare, complications such as D-lactate acidosis might develop (at least it can in humans).

This condition arises when bacteria in the gut produce too much D-lactic acid, leading to symptoms like confusion and difficulty walking.

How Much Probiotic Should A Dog Consume?

The current recommendation for dogs, based on their size and specific needs, is between 1 to 10 billion CFUs a day. This range ensures they receive adequate beneficial bacteria without overdoing it.

Probiotics are measured in what are called “colony forming units,” often abbreviated as CFUs.

This term essentially quantifies the number of live and active bacteria in a probiotic product.

When it comes to our dogs, determining the right CFU is essential.

Remember, the ideal number within this range might vary depending on factors like your dog’s age, dietary needs, existing health conditions, and the overall quality of the probiotic product you’re using.

Always ensure to check the product label for any specific dosage guidelines, and if in doubt, it’s always a good idea to consult with your veterinarian.

They can provide tailored advice, ensuring your pet gets the right balance for optimal gut health.

Prevention and What to Do if Overconsumption Occurs

As the saying goes, “prevention is better than cure.”

Here’s how you can prevent overconsumption and what steps to take if it happens:

Store Probiotics Safely

Probiotics should be stored much like any other medication or supplement:

  • Keep them in a cool, dry place.
  • Use childproof containers, but remember, what’s childproof isn’t always dog-proof!
  • Store them in high cabinets or drawers, away from a dog’s reach.
  • Consider using locks or childproof latches if your dog is particularly curious or dexterous.

Keep A Close Eye On Dosage Instructions

Sometimes, even well-meaning owners can give their dogs additional doses of probiotics. Whether its intentional (thinking more is better) or accidental.

Whether its offering too many scoops/treats/bites at a time, or not checking the the packaging of probiotic supplements carefully, it’s easy done.

So, make sure that whatever probotioc supplement you go for you are fully aware of the dosage instructions.

These are often provided by dog size/breed.

Monitoring Behavior and Physical Reactions

If you suspect your dog has consumed an excessive amount of probiotics, it’s essential to watch them closely:

  • Look for signs of digestive distress such as diarrhea, gas, bloating, or vomiting.
  • Monitor their appetite; a reduced appetite might indicate stomach discomfort.
  • Observe their energy levels. A lethargic dog might be experiencing internal discomfort.

When to Consult a Vet

If your dog shows any severe symptoms, such as prolonged diarrhea, vomiting, or any signs of pain, contact your vet immediately.

If you’re aware your dog has consumed a large amount of probiotics, even if they aren’t showing immediate symptoms, it’s a good idea to consult your vet for guidance.

Regular check-ups can also be an opportune time to discuss appropriate probiotic dosages for your dog’s size and needs, preventing potential mishaps in the future.


Probiotics can play a pivotal role in promoting and maintaining our dog’s gut health.

However, like any dietary supplement, they should be administered responsibly.

Overconsumption can lead to undesirable outcomes, even if overdosing is largely impossible.

For those looking for reliable, easy-to-dose options, I highly recommend Pawfy Probiotic Chews or Zesty Paws Probiotic Bites.

Both products stand out in the market, suitable for dogs of all breeds, ages, and sizes.

Their easy-to-understand dosage recommendations make them a hassle-free option.

With both products, for small dogs, a single chew or bite per day is sufficient, while larger breeds require just two per day.


And choosing quality brands like these not only ensures that your pet receives the beneficial bacteria it needs but also provides peace of mind.

You can be confident in the supplements dosage, effectiveness, and ease of use.

In the end, the goal is to enhance our dog’s health and well-being, and with the right probiotic products, this becomes an easily achievable aim.


How can I tell if my dog has had too many probiotics?

You will tell if your dog has had too many probiotics as you will likely observe digestive disturbances like diarrhea, gas, bloating, changes in appetite, or behavioral changes, likely being lethargy.

What’s the recommended dose of probiotics for my dog?

The recommended dose of probiotics varies by brand and product. Typically, dosage is based on a dog’s size: small dogs might need 1 dose daily, while larger dogs may require 2. Always follow the product’s label and consult a vet for specifics.
