What are Dog Probiotics For?

Probiotics are live bacteria that are beneficial for the body. They’re found naturally in your dog’s digestive tract, however, it can be difficult for canines to maintain a healthy level of probiotics on their own. So, most dogs can benefit from additional probiotics, which can exist in the food, treats, and supplements they eat.

Dogs typically need probiotics to help them digest food, absorb nutrients, and maintain a healthy immune system. Here are a few ways added probiotics can benefit a dog’s body:

  • Reduce digestive problems, such as diarrhea and flatulence
  • Reduce symptoms of food allergies
  • Help dogs recover from illnesses and injuries faster
  • Help manage disease symptoms
  • Improve mood and energy levels
  • Reduce stress

So, probiotics can give your dog a health boost from nose to tail. Most dogs will react positively to added probiotics, but if you’re unsure if you should give some to your furry friend, you should consult your vet.

Tips for Choosing the Best Probiotic for Dogs

Any of the probiotics for dogs mentioned above are good quality, but the best one for your canine companion may vary based on your dog’s needs and what you prefer.

Type of Probiotic

Like most supplements, probiotics come in a variety of forms. You can choose from soft chews, powders, or pills. Soft chews are generally the easiest to serve because most dogs will think they’re treats. However, if your dog is picky, it might be easier to mix a flavorless powder with their food or hide a pill in their favorite snack. All forms are effective, but not all dogs are interested in the same type.


All of these products have plenty of probiotics, but some of them include extra ingredients too. If you’re looking for something simple, you may want to go with a formula that only has the essentials. Yet, if you want the supplements to have a better flavor for your dog or additional health benefits, you may want to consider a product with more ingredients. However, you should always check to make sure the formula doesn’t include ingredients your dog is allergic to.


Probiotics are designed to help improve the digestive and immune systems. Some products also come with added benefits like promoting healthy skin and coats, battling bad breath, improving joint function, and boosting energy levels. So, consider which products have the best benefits for your dog.

Expiration Date

If you’re looking at probiotic supplements at the store, check the expiration date. Probiotic products contain living organisms, so once the expiration date has passed, the supplements aren’t as effective. Once you open a container of probiotics, you should also store it as directed to ensure it’s fully effective. Some opened supplements work best if refrigerated once opened, but you can check the label to be sure.


For some pet parents, price is essential. Supplements can be pricy, so you’ll need to find one that fits your budget. When looking at the prices of the probiotics, consider how many servings your dog will get out of the package. Sometimes, products may seem expensive, but they give you a good quantity for your money.

Frequently Asked Questions

Choosing the best probiotic for dogs is a big decision, so here are some questions to consider before making a purchase.

What’s the Difference Between Prebiotics and Probiotics?

Probiotics are the main part of these dog supplements. Probiotics are live bacteria that are good for your dog’s gut while prebiotics help sustain the probiotics. They work together to give your dog a full health boost, so having both in one supplement can be beneficial.

What is CFU in Dog Probiotics?

On the packaging of many dog probiotics, it’ll list the amount of CFU. CFU stands for “colony-forming unit,” which is the number of active microorganisms in each serving. Most products have anywhere between 1 and 10 billion CFU. Larger numbers of CFU will have stronger effects on your furry friend.

Can a Dog Take Human Probiotics?

No, a dog shouldn’t take human probiotics. Human probiotics aren’t dangerous for dogs, but humans and dogs benefit from different types of probiotics. So, to get the best results, you should give your dog probiotics specifically designed for canines.

How Often Should You Give Your Dog a Probiotic?

Most dog probiotics are designed to be given daily. However, you should read the label to determine the correct amount based on your dog’s weight. When in doubt, ask a vet to give you an accurate dosage.

Do Dogs Poop More When Taking Probiotics?

In some cases, yes, but it depends on the dog. Probiotics can firm up your dog’s stool and help them poop on a regular schedule. After taking probiotics regularly, a dog should be less likely to face frequent runny poop.

What Natural Probiotics Can Dogs Take?

Plain, unsweetened yogurt or pumpkin can be a good natural probiotic for dogs. You can mix one of those human foods with your dog’s food daily to improve their digestion, but you should ask your vet for a recommended dosage.
