Buying Guide

Important Features to consider when buying the best probiotic for your dog

Here are some things to consider before choosing a probiotic for your pooch:


Taste plays a vital role in chews. It becomes a useless inclusion to the diet of dogs when they don’t get to his body. There’s an added benefit for chews as they can be used as treats. You should also consider the chew-ability and taste if you decide to use them as treats.


In contrast to what you might think, syringes are not injections. This gives your dog a gel-like probiotic orally and much force will be used to shoot it into his mouth that he has no choice but to swallow it. This method cannot be hidden, but this will take the least struggle time. 


For most dog parents, they have a big selling point as they can sneak the powder into the food of most dogs easily without little or no restraints. So many companies make lots of powders flavored with chicken or beef, but if your pet prefers his food the way it is, them using the flavorless powders is highly recommended. 

Additional Nutrients

If something has been added to your routine already, this will be a great way of incorporating other nutrients through which your pet dog can get some benefits. You may include some multivitamin that includes a probiotic as well. Mind you, this is not very common, since the bacteria present in the probiotic may fail to blend effectively with other ingredients.

How to Pick the Best Probiotic for your Dog

When choosing probiotics for your pooch, there are certain things to keep in mind: 

Guaranteed CFU: The product’s label should indicate and guarantee the number of CFUs (Colony-forming units) in billions or millions per gram. 

Species and Strain: The ingredients listed on the product should indicate the bacterial species and strain like Lactobacillus acidophilus.

Contact of the Customer Service: The website of the manufacturer or the packaging of the product must include their customer service contact, so you can reach out to them with your questions.

Storage Recommendations and Expiration Date: There must be an expiration date or a “best before” written on the product. Storage conditions and time (i.e. excessive cold or heat) could reduce how viable some of these bacterial strains are. It’s best to keep your probiotics safely in a refrigerator 

Tips for Keeping the Cultures of Canines Alive and Well

Always take note that probiotics are also referred to as living organisms. Because they evolved to live in the digestive system of your dog, they may die when kept in a box of made to sit in your cupboard. Therefore, when buying probiotics for dogs, ensure to:

  • Keep it in a cool and dry place
  • Expired products must be discarded; they are less likely to have many live CFUs
  • Go for brands explaining the quantity of live CFUs when the product expires 
  • Use brands that offer protective shields

Frequently Asked Questions

What is a probiotic for dogs?
A probiotic is a bacteria that doesn’t cause or bring harm to your dog and could protect them against harmful bacteria.

They occur naturally; however, occasionally the body becomes unbalanced which will result in some consequences.

Do these Probiotics really work?
Yes, they do. They do a lot more than you can ever understand. But logically speaking, it’s not a drug, nor is it a miracle.

In cases of serious health issues, your vet will prescribe an actual medication that will work more effectively than a probiotic.


Just like humans behave, dogs depend on a perfectly functioning immune system to ensure that substances and organisms causing diseases are managed effectively at the cellular levels. Now, it is an obvious fact that about 70% of the immune system’s main disease-fighting cells are situated in the lymph vessels lining the gut or gastrointestinal tract. This is why the optimal functioning of your dog’s immune system must be maintained. A gut functioning effectively maintains the integrity of cells of the immune system, helping your pet to be more active and live healthier lives.

Thankfully, there’s no need to visit your vet to ensure your dog’s gut stays equal to the task, all you need is a reliable probiotic supplement, specially designed to provide dogs with good bacteria to ensure it stays healthy. With our ten best probiotics for dogs reviewed above as well as our buying guide, you shouldn’t have any problems making your decision.
