Dogs, like humans, also need good bacteria to be healthy. Overall well-being is all about proper balance after all, including the balance of good and bad bacteria in a dog’s system. Microbial imbalances in canine often cause gastrointestinal problems, including diarrhea, flatulence, and even canine halitosis. Health is wealth, always, and so give your dog probiotics to help bring back their system’s homeostasis, especially during stressful times or sick conditions.
As a precautionary measure in probiotics administration, besides consulting the family vet, learn how to read the label first. Some live microbes when combined together balance out their positive effects. Other bacteria strains even have limited probiotic activities, which are not worth the price. Practice looking at labels as you read our user-friendly dog probiotics guide below:

Best Probiotics for Dogs Buying Guide & FAQ
What You Should Look for in Probiotics for Dogs
The right probiotics for dogs should always contain live organisms, not dead ones. Ideally, you would want a minimum of 20 million colony forming units of dog gut-specific bacterial or yeast strains. Twenty million may seem too many, but you have to realize that the probiotic supplement will pass through the highly acidic environment of the dog’s stomach. The more colony forming units or CFUs you give to your dog, the greater are the chances that there will be sufficient numbers of live microorganisms reaching the gut.
In addition to the number of colonies forming units of live microorganisms, it is equally important to look at the probiotic strains present in the supplement. Bacillus coagulans and Enterococcus faecium are just two of the clinically important probiotic organisms in dogs. Other probiotic organisms that are very beneficial to dogs can include Bifidobacterium animalis AHC7, Bifidobacterium bifidum, Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus salivarius, Lactobacillus reuteri, and Lactobacillus fermentum.
These are just some of the strains of microorganisms that have been proven to be very beneficial for dogs. If you see other probiotic strains in the supplement that you are going to buy, we strongly recommend researching for it first to find out just what it can provide to your dog and whether or not it is safe to give to your pet.
Sometimes it is better to look for probiotic supplements that come with other ingredients such as substances designed to improve joint health, encourage brain development, boost immune functioning, and the like. However, just make sure that these substances do not interfere with the principal action of the probiotic organisms.
One critical factor that you should never forget when picking a probiotic supplement for your pet is the credibility and trustworthiness of the manufacturer. As much as possible the product should be manufactured from a facility that is certified as GMP. Moreover, it is best to get a product that’s made in the US, although this can be tricky. There have been issues wherein the product is guaranteed to have been made in the US, but the ingredients are sourced from China. Do your research very well especially if you’re not familiar with the brand of the probiotics you want to buy.
Some pet parents also choose a product that is more convenient for them to administer. Some will go for soft chews especially flavored ones, although there may be some issues when it comes to the use of artificial flavorings. Some individuals prefer to use powdered formulations of prebiotics as this can be easily sprinkled into the dog’s food.
Also, check the product’s expiration date. Pick a product with a much longer expiration date, although this may be tricky considering you’re talking about live microorganisms in the formulation. It is critically important to have a good understanding of how the product should be stored once opened. Lastly, you should have a clear idea of where to get in touch with the manufacturer if something goes wrong.
Health Benefits of Probiotics for Dogs
Probiotics are nothing more than the same healthy microorganisms that live in your dog’s gut where they serve as ‘good’ bacteria. It is for this reason that giving probiotics to your dog is largely considered as very beneficial. Here is a list of what probiotics can do for your pet.
- Improves the overall function of the digestive system, allowing food particles to be broken down and the nutrients absorbed by the blood more efficiently.
- Probiotics aid in the more effective evacuation of stool so your dog will not feel constipated.
- It can help reduce the risk and incidence of food intolerance as well as any accompanying signs and symptoms.
- It reestablishes the balance in intestinal flora so that ‘bad bacteria’ can be effectively neutralized.
- Can reduce the severity of intestinal inflammation which can result in the resolution of diarrhea or even constipation.
- Can improve overall energy levels for the dog because of the improvement in the absorption of energy-dense nutrients while also eliminating or minimizing the effects of a variety of chronic inflammatory conditions.
- Helps neutralize and break down toxins and potential carcinogens found in pet food.
- Improves canine breath and prevents the development of bad breath or halitosis in dogs.
- Can contribute to improvements in skin and coat health by making sure that the necessary nutrients are absorbed and delivered by the blood to the dog’s skin and coat.
- Improves immune functioning especially since more than 70% of the cells of the immune system of the dog are found in the gut. Improving the immune function can also help reduce the incidence of allergies, hypersensitivity reactions, and even infections.
- Promotes the production of B vitamins, biotin, and folic acid.
Potential Side Effects of Probiotics for Dogs
Probiotics are safe for dogs. Unfortunately, it is not uncommon that things can happen along the way. This is especially true in probiotic supplements that may contain ingredients other than probiotics. It is possible that the dog is showing the side effects of any of these ‘other’ ingredients and not necessarily the probiotic organisms themselves.
In such instances, it is possible to see diarrhea, constipation, gas, or even bloating in dogs. It is for this reason that products with only probiotics as their ingredients are way better than those that have multiple ingredients as you’ll never know which of these substances your dog might react to.
Best Probiotics for Dogs FAQ:
Q: What are probiotics?
A: These are live microorganisms, specifically bacteria and yeast organisms, which help keep the balance of good and bad bacteria in the intestines. Everyone has this notion that germs are naturally bad. However, microorganisms reside in every region in the dog’s body. They carry out different functions such as the synthesis of certain vitamins and the maintenance of immune system health.
The intestines are naturally filled with germs, both good and bad. When a dog is given antibiotics, the bad bacteria are killed. Unfortunately, some of the good bacteria are also killed in the process. This leads to what they call antibiotic-associated diarrhea. Probiotics can help ‘replenish’ these lost good bacteria so that balance can be reestablished.
Ideally, you would want a healthy balance of good and bad bacteria in the intestines. If there are more bad bacteria, then the dog can present with a variety of conditions we don’t normally associate with the overgrowth of bad bacteria such as bad breath, itching, skin allergies, gas, low energy, and many others. Probiotics can help restore such balance so that these problems will also naturally go away.
Q: Are human-grade probiotics safe for dogs?
A: No! The intestinal florae found in dogs are very different from the ones found in human intestines. To be more specific, dogs require very specific strains of bacteria and yeast that are highly compatible with their intestines. Just because both human- and pet- grade probiotics contain Lactobacillus or Bifidobacterium doesn’t automatically give you the right to give your probiotic supplement to your dog. If you give human-grade probiotics to your dog you might as well give it the kind of organisms that will make it very sick instead of helping it improve its digestive and immune system capabilities.
Q: When should I use probiotics for dogs?
A: Probiotics can be given to dogs on a daily basis, although veterinarians usually prescribe them only when the dog is having some digestive upset, is taking steroids or antibiotics, or is experiencing stress. However, we have seen a lot of pet parents who gladly share their stories about the tremendous benefits of giving probiotics to dogs on a regular basis and not only when they have digestive problems.
Q: Can I give probiotics to my puppy?
A: Yes, you can give probiotics to your puppy. The intestinal tract of puppies, just like human babies, is still relatively sterile. Giving them probiotics can help strengthen the health status of their still-immature gut while improving their overall immunity. A healthy gut also helps facilitate the better absorption of nutrients from the mother dog’s milk while paving the way for other more complex food molecules in puppy food.
