How To Pick The Right Probiotic For Your Dog

When it comes to probiotics, there is no one size fits all. There is also a wide range of products out there and most dog parents usually get confused about which to pick.

Choosing the best probiotic for your canine is a bit tricky, but you can scale though with ease when you know the vital things to look out for. A dog probiotic should have a couple of vital things.

Here are some of the important things you need to consider when looking for a probiotic for your dog:

Colony Forming Unit (CFU) Count

The colony-forming unit (CFU) is one thing you should never ignore when looking for an ideal probiotic for your canine. All dog probiotic products have different colony-forming unit counts. Some products contain hundreds of millions of CFUs for every serving while others contain up to billions of CFUs.

Sometimes, this can be misleading, as you might consider a product that contains 400 billion CFUs as an exceptional product. Nevertheless, that value might be for the whole pack or container and not each serving.

For instance, you might have a 500-gram jar of probiotics that says it contains 500 billion CFUs. What this actually means is that the whole jar (which is 500 grams) contains 500 billion CFUs, which is the same thing as 1 billion CFU per gram.

However, the CFU count in the product is not the main issue. The main issue is that many pet parents do not know the CFU count their dogs need. Since there is no way to determine the exact amount that is enough for your dog, some experts have recommended you start small.

They recommended you start small and increase it gradually until you start seeing your desired result. For general maintenance, some experts say a dog needs about 1 to 4 billion CFUs. If your dog has IBS, you would need to increase the count while dogs with diarrhea need a lower count.

Bacterial Strains

There are dozens of different gut bacteria species that can be added to a probiotic. Some species compete with each other while others work pretty well together. Some dogs might not react to some species.

As such, it is important that you go for an option with multiple species. Nevertheless, the effect of too many bacterial strains might not be pleasant on the digestive health of your dog.

This is why professionals recommend you start with fewer strains and then increase it gradually. However, the product you opt for should contain enough blend of Lactobacilli and bifidobacteria species, as their effects have been studied extensively.

Prebiotic

Many probiotic products also contain prebiotics, and this helps the probiotic bacteria to survive and thrive. It is not advisable that you opt for a product that contains prebiotics. This ingredient can boost the effectiveness of the formula significantly. It can also make it last longer.

Form

Probiotics come in different forms. You can find them in a chewable, powder, capsule, or syringe form. The two most common are chewable and powder forms:

Chewable

For the chewable probiotics, taste and smell play a major role. These forms of probiotics are often used as treats. Many pet parents give it to their dogs as treats for them to chew.

 If the probiotic does not have a great smell or taste, you might have a hard time feeding it to your dog, as it might reject it. Hence, you need to make sure the product has great, appealing taste and smell.

You can read reviews to know if the product tastes and smells good. Furthermore, you should consider the chew-ability, as some products are too hard for dogs to chew.

Some pet parents even find it difficult to break some products into smaller pieces. To make it easy for your dog to chew, you should go for an option that is a bit soft, but not too soft.

Powder

Probiotics that come in powdered forms are much easier to administer, as you can just sprinkle it on your dog’s food. It will not have any effect on the taste and smell of the food, and your dog will not notice it also. Some of them are odorless while others come with different flavors. There are chicken or beef flavored powders.

Nevertheless, if your dog does not like the flavor options, we recommend you stick with the powders without any flavors. If you really want to use the flavored powder, it is best you start gradually and then work your way up.

We suggest you go for an option that works best for you and your dog. Some dog owners prefer the chewable form because it is more convenient for them and it helps to clean their dog’s teeth as it chews. However, a tasteless powder form is the best option for very fussy dogs.

Additional Nutrients

It is best to go for products with additional nutrients. For instance, you might need a product that comes with multivitamins, minerals, antioxidants, and more. These types of products are rare but they tend to offer more benefits. Some products also come with digestive enzymes, and these are also highly beneficial.

Frequently Asked Questions (FAQs)

Are Probiotics Effective On Dogs?

Probiotics are highly effective for dogs. However, you need to find the one that is perfect for your dog.

When Do I Use Probiotics For My Dog?

You can use probiotics when your dog is sick or stressed. You can also use it as a daily supplement to balance the immune system and digestive health of your dog continually.

Can I Give Human Probiotics To My Dog?

There are no studies that human probiotics are harmful to dogs. Nevertheless, veterinarians and top experts highly recommend you give your dog probiotics formulated for only dogs. The digestive system of a human and that of a dog are not the same; hence, you should stick to that made specifically for a dog.

Final thoughts

Paying close attention to the health of your dog is very important. Probiotics for dogs are very useful, as they help boost the digestive health of your dog and improve its overall wellbeing. We hope you are able to find a probiotic for your dog from the products reviewed above.

While all the products are great, our top recommendation is the Purina Pro Plan FortiFlora Probiotic for Dogs because it is very effective and very easy to administer.
