dog food with probiotics

One of the latest human trends to go to the dogs (literally) is probiotics.

But these microorganisms aren’t just another fad; they have the potential to help improve your dog’s health in a number of ways. You can administer them on their own via supplements, or you can select a food containing them to make things easier — and that’s what we’re going to talk about today.

We’ll identify some of the best dog foods with probiotics and help digest the facts (and fiction) surrounding probiotics below.

What Are Probiotics?

probiotic for dogs

Just like your digestive tract, your dog’s belly is full of billions of good and bad bacteria. This natural harmony contributes to overall health in what’s referred to as your dog’s microbiome.

But sometimes, this delicate bacterial balance is thrown off by antibiotics, illness, or stress, leading to digestive upset, irregularity, and other unpleasant side effects that can impact your dog from nose to tail. 

This is where probiotics can help. 

Probiotics consist of naturally occurring gut bacteria and yeast to help right the balance of organisms living in your dog’s digestive system and restore proper digestive function. This improved digestive landscape also promotes overall health and wellness, potentially leading to better absorption, less gas, and more.

Probiotics are relatively common amongst us humans today, with many supplements and even yogurts dedicated to our gut. These probiotic supplements also exist for dogs, though it’s far more convenient not to have to add another supplement to your routine.

You might be surprised to discover your dog’s current food may already contain probiotics too, so check the bag to be sure.

In dog probiotics, the most commonly included bacteria include:

  • Bifidobacterium lactis
  • Lactobacillus casei
  • Enterococcus faecium
  • Lactobacillus acidophilus

These added bacterias are noted within a food’s ingredient list, typically towards the end (they should technically be printed in italics, but this isn’t always the case on dog food labels).

This bacteria won’t make you or your dog sick, but they’re sensitive to heat, moisture, and air, so follow the food’s storage instructions.

One Bacterial Strain or Several? Which Approach Is Best?

Some probiotic-inclusive dog foods (and supplements) contain only a single bacterial strain, while others include a mixture of several different strains. This leaves many owners wondering which approach is best.

Unfortunately, there isn’t a broad consensus among vets or human doctors about which approach is best. But broadly speaking, the trend seems to be a “shotgun” approach, in which a variety of strains are included.

Ultimately, you’ll just have to discuss the issue with your vet and make the best choice you can on behalf of your dog.

For most owners, a multi-strain food will probably be the easiest choice. However, you might choose a single-probiotic food over a varied one if your dog’s showing an imbalance in a particular bacteria strain, which is detectable via a stool sample.

You might also opt for a single-source food if your vet recommends it, as certain bacteria can aid more with some issues than others.

What Health Benefits Do Probiotics Provide?

dog food probiotics

Unfortunately, research into the benefits probiotics provide dogs is still in its infancy. However, positive anecdotal accounts abound, and most of the research that has been conducted has yielded positive results (we share some additional studies below).

Generally speaking, it is thought that probiotics may provide the same benefits to our four-legged friends that they do for us. Essentially, they help combat or prevent gut issues that can affect wellness from head to toe. 

Think about it: When your belly is feeling off, you feel off, right?

Canine probiotics may aid in: 

  • Regulating digestion
  • Reducing gas
  • Alleviating diarrhea 
  • Eliminating foul breath caused by stomach bacteria overgrowth
  • Protecting stomach flora

Remember: If your dog is experiencing changes in eating, pooping, or passing gas, contact your vet for an exam to rule out underlying conditions.

Never give your dog a supplement made for humans, either, and don’t feed probiotic yogurt without checking with your vet, as hidden artificial sweeteners can be dangerous, and dairy can cause gastrointestinal upset.

When Are Probiotics Used in Dogs?

With the potential benefits, it’s natural to have your interest piqued surrounding probiotics. In some cases, certain dogs see marked improvement by introducing dietary probiotics, while the changes may be less noticeable in others and act more as a preventative than a solution. 

Probiotics are given to dogs in several situations, including:

  • Normalizing gut flora: If your dog’s digestive tract is running a little sluggish, probiotics may help restore its balance. Signs of an imbalance can include diarrhea, constipation, and excessive gas. This is why probiotics are so common in dog foods designed specifically for gassy dogs.
  • Post-antibiotic treatment: As we all know, antibiotics can wreak havoc on our tummies, and it’s no different with doggos. Essentially, broad-spectrum antibiotics end up killing off the good bacteria along with those that are causing illness. Probiotics can help return your dog’s gut to its natural state after antibiotics run their course.
  • Reducing sensitivity symptoms: Some dogs with super sensitive systems may go through bouts of stomach unrest. Probiotics can boost gut health and possibly alleviate symptoms and prevent future stinky situations.
  • Post-illness gut boost: Probiotics can help dogs who’ve recently been ill get back on track, especially if they were suffering from a gastrointestinal problem.
  • Preventative use: By bolstering your doggo’s tummy, it can ward off illness and leave her feeling in tip-top shape. Old dogs can particularly benefit in this area, as a peak-performing digestive tract means more energy, less discomfort, and better nutritional absorption.
  • Calming a stressed system: Some events, such as moving, being adopted to a new home or being kenneled can cause stress-induced diarrhea. Probiotics can help ease this not-so-fun problem.

As always, consult your veterinarian before trying probiotics or any supplement, for that matter. Your dog’s existing medications, supplements, or conditions may not be compatible with probiotic use. 

Are Probiotics Safe for Dogs? 

are probiotics safe

You should always consult your vet before starting a supplement regimen or switching dog foods — especially if your pooch already has a health issue.

But yes, canine probiotics are largely considered safe for dogs.

Thinking about willingly feeding your fur kid bacteria can be alarming, but probiotics contain good bacteria that already exist within your canine’s stomach. Basically, probiotics function like more of a good thing. For example, you might take a daily multivitamin when you’re already getting nutrients in the food you eat.

However, as we discussed above, don’t offer your dog human probiotics. Our stomachs differ from doggo ones, so the included bacteria in a human probiotic differs from a canine one. You might accidentally cause certain belly issues to get worse or cause other harm.

Do Probiotics Actually Work for Dogs?

Again, there isn’t a ton of research yet available regarding probiotic use in dogs.

Nevertheless, several scientific studies have demonstrated the efficacy of canine probiotics, including a 2009 one noting benefits seen in dogs suffering from idiopathic diarrhea after probiotic administration.

Another study specifically linked the canine probiotic Bifidobacterium to potential improvements in canine gastrointestinal health. 

As with any supplement, probiotics aren’t always a surefire fix, but they’re worth a shot if your vet green-lights them.

Are There Alternatives to Feeding a Food Containing Probiotics?

Absolutely! While a dog food containing probiotics is convenient, we understand hesitating to run out and try a new kind, especially if you have a pickier pupperoni at home.

If you and your doggo are happy with his existing food, you can still tap into the possible benefits of probiotics by:

  • Feeding a dog-friendly yogurt: Yogurt is an easy way to sneak some probiotics into your doggo’s bowl, but remember to check your labels to avoid xylitol or other toxic artificial sweeteners. The secret here is to stick as close to plain yogurt as possible. Be mindful of portion size, as calories add up quickly and stomach upset is a possibility with too much dairy. 
  • Using a probiotic supplement: Typically packed into a tasty tablet or offered in a capsule, these healthy bacteria boosters can be fed on their own or hidden in your pup’s favorite snack, like dog-safe peanut butter. Follow storage instructions closely to ensure the best results, as probiotics require special handling.
  • Feeding a prebiotic: Prebiotics are fibrous ingredients that serve as food for probiotics, so they can help with your dog’s natural probiotic growth. They’re a great alternative if you’re looking to boost your dog’s existing gut flora. Some owners opt to feed prebiotics and probiotics, but always check with your vet to see what’s best for your pup.
