Probiotics for dogs shouldn’t be complicated or risk causing further disruption to your dog’s sensitive stomach; it should be kept simple! This is why Honest Paws Pre + Probiotic for Dogs is our favorite canine probiotic! 

First and foremost, it contains a whopping 6 billion CFU*. Although it is rarely the-more-the-merrier with bacteria, that’s definitely the case with this probiotic powder that should help keep your dog healthy inside and out!

Why Are Probiotics For Dogs Needed? 

You may have heard your veterinarian, a breeder, or a friend talk about probiotics. But, what is it? Put simply, probiotics are beneficial, or friendly, bacteria!

Humans and animals have billions of bacteria in their intestines. Some can cause disease, but probiotics help with everything from the digestion of food to fighting infections, strengthening the immune system–and some even help make vitamins and nutrients essential for the body!

All in all, this complex system is called the microbiome, and it’s unique for every. single. dog. Probiotics, the beneficial bacteria, are already there. Still, more can be added to your dog’s system to help it prevent and combat any microbiome-related disorders, simply by helping bring the microbiome back into balance. 

Some of the disorders that can occur when the microbiome is affected include: 

Suppose your dog is suffering from an unbalanced microbiome, possibly due to a lack of probiotics. In that case, you can luckily add probiotics to your daily routine and help bring the gut back in balance! 

Just remember that probiotics aren’t an easy fix solution. If your dog is suffering from diarrhea or other gut-related diseases, you can start with probiotics, but you should always consult a veterinarian if the issue persists! 

Our Top Picks When it Comes to Probiotics for Dogs

The Five Different Types of Probiotics for Dogs

As there are billions of bacteria in the gut, it can be challenging to determine which ones your dog needs a boost of. Generally, the most common types of probiotics found in the intestines include: 

  • Lactobacillus casei 
  • Lactobacillus acidophilus
  • Bifidobacterium breve
  • Enterococcus faecium
  • Bifidobacterium lacti

These probiotics can all be given to your dog in different ways and forms. The most common ones are: 


Probiotic pastes are often an easy and fast way to give your dog probiotics, with most dogs loving the sweet-tasting paste that comes out of the tubes. One minor issue is that it can sometimes become a bit of a mess! 


Probiotics for dogs can also come as powders that will need to be mixed in with their food. Here the significant benefit is that the powdered probiotics are protected from any exposure to the environment around them, including air and moisture. However, some dogs may not like the powder, so it very much depends on the dog!

Food types with probiotics 

You may have heard the old advice of eating yogurt when you’ve got an upset stomach. The same goes for dogs! A good source of natural probiotics is yogurt or kefir, as long as they have live cultures. Just make sure it is entirely plain, with no artificial sweeteners!

Pills and dog treats

Probiotic pills are also available! Pills can often hide in a pill pocket or another delicious treat you know your dog will swallow whole. Just make sure your dog actually swallows the probiotic pill – and not just the delightful treat

Dog food with probiotics 

Some dog food brands have started adding probiotics for dogs in dog food! This is quite possibly one of the easiest ways to add probiotics to your dog’s food. Another benefit of dog food with probiotics is that it often also contains prebiotics, which is nutrition for the beneficial bacteria/probiotics in the gut!

Just remember that bacteria are pretty sensitive microorganisms. If the food hasn’t been made correctly, the probiotics can be killed off during production, making sure to choose a quality product.

Best pick for the smaller dogs

Non-GMO verified ingredients. 


Probiotics need to help your dog balance its sensitive microbiome, without filling it with untoward chemicals and fillers and that’s why I am a sucker for short ingredient lists–and of course, that’s why Honest Paws Pre + Probiotic is my top pick! 

It is developed by a veterinarian with a Ph.D. in nutrition and gut health in dogs to put everything in this probiotic a dog needs for a healthy gut microbiome–and nothing it doesn’t need. While keeping the flavor of bone broth–that most dogs will like!

It is also important to note that most healthy dogs fed high-quality dog food diets should not necessarily need probiotics every single day to stay happy and with a normal stool. It can for some be beneficial and is (almost) never harmful, but most dogs should be alright without. This is why this powder gains another extra point, for being shelf-stable for up to two years–so don’t worry about using it all at once!

In the end, probiotics are there to support our dogs through gut issues and keep them healthy, which is precisely what these ten we’ve talked about do!
