If you’re looking for the best options, we reviewed three of the best picks in the market. We also discussed a buying guide and more valuable tips for pup owners.

Why and when are probiotics necessary for a puppy?

Probiotics are live cultures that include healthy yeast and bacteria. All of this helps improve your dog’s digestive health. Although these are bacteria, it’s the good type that benefits your pet. Aside from canines, probiotics are also suitable for humans.

Aside from this, probiotics also bring various perks like the following:

*Antioxidant properties
*Better resistance to diarrhea
*Endurance against stress
*Resistance to food poisoning
*Stronger immune system.
*Better coat health

There are more benefits to giving your dog probiotic supplements. Just make sure that you pick the right one that suits your pup’s needs.

Can I give human probiotics for my puppy?

Actually, human-grade probiotics have very little difference to probiotics given to dogs. However, some supplements have a higher dose and different ingredients. Always check it first to prevent any untoward side effects to your pet.

As much as possible, consult the vet if you’re planning to administer non-canine probiotics to your pooch. Like human babies, you have to be very careful about what you give your puppy.

At all times, purchase a probiotic supplement made for puppies. Besides, there’s a good reason why there’s a specific formulation for dogs.

Are probiotic supplements safe for puppies?

As long as you purchase one that’s made for puppies, your doggo should be fine. If you’re in doubt, nothing beats the expertise of a veterinarian.

Also, make sure that the supplement is FDA-approved and tested to be safe for canines. You can also try giving natural probiotic sources to your dogs like plain Greek yogurt, artichokes, honey, and leeks.

However, dog foods don’t usually meet the needs of your pooch when it comes to probiotics. This is why you can supplement with various probiotic products made for canines.

The Association of American Feed Control Officials (AAFCO) refers to probiotic products as ‘direct-fed microbials’.         

If your pooch is taking antibiotics and other medications, consult with a vet first before giving it any probiotic product. As much as good bacteria are beneficial, it may have contraindications on your dog’s health.

PREbiotics vs. PRObiotics

Many pet owners get confused about the difference between prebiotics and probiotics. Prebiotics are a dietary fiber that serves as fertilizer for the good bacteria in the dog’s gut.

On the other hand, probiotics are live bacteria that will boost the health of the digestive tract. Probiotics can live on prebiotics, making these two substances indispensable for your dog’s gut health. Some of the examples of probiotics are lactobacillus and bifidobacterium.

So which one does your dog needs? Both, actually. For pups with diarrhea, both probiotics and prebiotics can help alleviate the symptoms. In fact, you can find probiotic products that are also packed with prebiotics for a double dose of benefits.

Should I consult a vet first?

Yes! You should always consult with a veterinarian before giving your pup any type of supplement. The same goes if you’re switching the puppy to a new diet to cure diarrhea.

Veterinarians can help determine the cause of diarrhea and what you can do to prevent it. This way, you can also avoid any harsh side effects.

Potential side effects of probiotics

Probiotics are relatively safe among dogs. Also, it’s quite uncommon for supplements like this to cause adverse side effects. Still, being cautious will go a long way, especially for pups with diarrhea and a sensitive stomach.

Usually, the root cause of the adverse side effects of probiotics is the other ingredients added. Since probiotic products for dogs are made into snacks and treats, you have to read the label always.

If your pup becomes gassy, constipated, or bloated after taking a probiotic product, the ingredients may be causing such problems.

[Buying Guide] Probiotics for puppies with diarrhea

If you’re looking for the best probiotics for puppies with diarrhea, make sure that you consider these points first:

-Go for a dry type

As much as possible, choose a dry or semi-moist product. You can get a powder that you can mix with your doggo’s food. It’s easier to administer, and it doesn’t stand the chance of spoilage. Aside from that, probiotics in powder-form have been stabilized and will be activated upon reaching your dog’s intestines.

Also, you can look for a semi-moist treat so you can replace the snack of your pooch. However, this doesn’t bear as much bacteria as powder products. Still, it’s an excellent choice for pups and dogs that don’t need very high doses of live bacteria.

Again, always check the ingredients and make sure that nothing will irritate your dog’s tummy.

-Check how much bacteria are in it

Each probiotic product comes with a specific amount of live bacteria. The more bacteria the product has, the better it is for your puppy or adult dog. Usually, probiotics are measured by CFUs or colony-forming units. Aim for the highest possible CFUs on the product you’ll purchase.

Also, check what type of live bacteria is present on the probiotic product. It could be lactobacillus strains, Bacillus coagulans, Enterococcus faecium, and more. Most of the time, these products will have two or more live bacteria.

-Look for combination prebiotics and probiotics

If possible, look for a product packed with a combination of prebiotics and probiotics. This way, the live bacteria will have a place to thrive. The dietary fiber will also help stiffen the stool of your dog to reduce the onset of diarrhea.

Anyway, you only need a small amount of prebiotics for a supplement. And although it comes in small doses, it’s very crucial in the overall wellness of your dog.

-Consider the manufacturer’s trustworthiness

Although the brand doesn’t necessarily embody the quality of the product, it will give you an idea of the probiotic product’s reputation. Also, many dog owners trust a specific brand due to its ingredients and production process. Some of the great options are Purina, NUSENTIA, and Zesty Paws.

-Look for minimal ingredients

If you’re opting for chewable treats, always look for one with minimal and natural ingredients. This way, your puppy is less likely to experience allergic reactions. It’s also a good decision, especially if your doggo has intense diarrhea.
