As dog lovers, we are increasingly turning to supplements for added canine nutritional benefits. Our dog's digestive health, powers not only our dogs emotional wellbeing, but also our own.

Inconsistent stools, diarrhoea, constipation and stomach upsets are among the most common signs of digestive discomfort in dogs. This may be reduced or significantly improved with the addition of a probiotic supplement.

Probiotics contain "good" bacteria meant to improve your dog’s gut flora. They have a variety of claimed beneficial effects, such as reduced gas and firmer stools.

Buying Advice for Dog Probiotic Supplements

A quick word about supplements for dogs.

We've found that supplements can be a very confusing area to investigate. Many of the supplements and their ingredients have real theoretical benefits.

However, we've found that whilst independent research is still limited, there is an abundance of anecdotal evidence to help dog lovers select a product.

Here are some general guidelines to bear in mind when you are choosing a probiotic supplement for your dog :-

🐾 Look for several bacteria strains

There are many different strains of beneficial bacteria, and each one offers different benefits. For example, some strains can help with digestion, while others can help boost the immune system.

A good probiotic will contain a variety of strains to provide your dog with the most comprehensive benefits.

🐾 Know the difference between probiotics and prebiotics ?

Probiotics and prebiotics are often misunderstood. Probiotics (sometimes called microbiotics) are foods or supplements that contain a source of live, beneficial bacteria. Prebiotics, provide sustenance to these bacteria.

🐾 Choose a palatable option

Do you have a picky pup ? Our review of dog probiotic supplements includes a range of tablets, powders and chews so you can decide which is most palatable for your dog - because you know them best!

🐾 Select a probiotic with a money-back guarantee.

That way, you can try the supplement and see if it works for your dog without any risk.

🐾 Chat to your vet

We recommend talking to your vet about which probiotic is most suited to your dog's needs.

All the brands featured in our review can be bought as a one-off purchase or you can take advantage of their subscription service to make substantial savings.

Our Picks of the Best Probiotic Supplements

1. Best Overall Dog Probiotic

Pooch & Mutt

Pooch & Mutt is one of the UK's most award-winning premium pet food brands. Their focus is on natural, functional products and their first ever product - Bionic Biotic features in first place in our review.

Bionic Biotic is one of their best sellers, so let's take a closer look at why so many dog lovers swear by it.

Bionic Biotic from Pooch & Mutt

A vet recommended probiotics for dogs, it's packed full of natural ingredients and designed to be sprinkled over your dog’s food.

Perfect if your dog dislikes taking tablets, as it's super easy to incorporate into your dog’s normal feeding routine. If you feed kibble then you can mix the powder with salmon oil before adding to dry food to help it 'stick'.

The main reason we've awarded it top place in our review is because it's a multipurpose supplement with a comprehensive range of benefits for your dog including -

⭐️ Improves digestion & solid stools

⭐️ Prevents itching & scratching

⭐️ Improves skin & coat health

So ultimately, by adding this one supplement to your dog's diet, you can address several common problem areas at once.

In testing over the course of 2 months, we found a marked improvement in our testers stools. All poop throughout the day was solid and the frequent scooting stopped.

Bionic Biotic contains chicory root which is an excellent fibre source. This natural fibre helps increase the size and weight of your dog's stool whilst softening it to make it easy to pass. So it can relieve constipation, diarrhoea and end that dreaded scooting !

Another key ingredient, Salmon Oil, is a rich source of Omega 3 fatty acids which can help lessen inflammation caused by allergies or other skin issues.

Ultimately, Pooch & Mutt are so confident in Bionic Biotic that they offer a money back guarantee for on-line purchases.

It's worth mentioning that Pooch & Mutt also offer a range of three meaty probiotic dog treats too.

Our Verdict - With many lovers seeing a difference within 3 weeks and countless 5 ⭐️ reviews talking about digestive problems disappearing, we think Bionic Biotic is a great all-round super supplement.

Form : Powder

Quantity: 200g (lasts 10-25kg dog a month)

2. Best Probiotic Range

Buddy & Lola

Buddy & Lola offer a wide range of health and wellness supplements for dogs aimed at some of the more common health concerns including joint mobility, digestive issues, dental health, anxiety and allergies.

Their best-selling product is Super Tummy Daily which is adored by dog-lovers and receives rave reviews.

Puts Purest Prebiotic & Probiotic Powder for dogs

Available as a powder to sprinkle over food or alternatively as a daily chew. We love that Buddy & Lola provide an option so if you have a super fussy dog, you can chose the form that you think will be most palatable.

Super Tummy combines beneficial bacteria, digestive enzymes, prebiotics and probiotics in the optimal blend to heal your dog's digestive system and to maintain a healthy, balanced gut microbiome.

Regular use will help to:

⭐️ Boost beneficial gut bacteria

⭐️ Supports healthy ears & paws

⭐️ Maintain firm, healthy stools

⭐️ Support digestive health

In testing, the chews went down a treat ! They are plant based which is a great choice if you have a dog with sensitivities, but cleverly they are crafted with the alluring aroma of bacon, which was a massive hit.

Price-wise, the chews work out slightly cheaper than the powder, particularly if you have a large dog.

Buddy & Lola Super Tummy Instant probiotic for dogs

The third Buddy & Lola product we want to slip into this review is one for your dog First Aid kit.

Of course, the first thing to be said about Super Tummy Instant is that it's not a probiotic, Super Tummy Instant is a supercharged, veterinary-strength poop support for those times where you need instant results.

All dogs suffer with diarrhoea and upset tummies from time to time and Super Tummy Instant (as the name suggests) offers a short term solution which can then be followed up with their probiotic Super Tummy Daily on an ongoing basis.

For a full list of active ingredients in all their products and how they can help your dog, take a look at the Buddy & Lola website.

Our Verdict - With all-natural nutrients, approved by vets, a 30 day no fuss money-back guarantee, free delivery with orders over £30 plus a great value subscribe & save option including a free supplement storage tin, (take a breath) Buddy & Lola are definitely worth a closer look.

Form : Powder or Chews

If you have a Goldilocks level fussy dog when it comes to tablets, then take a closer look at Yumi Dogs. Their meaty dog chews offer all the benefits of traditional hard-to-swallow tablets in tasty treat form.

Yumi Dogs Probiotic chews for dogs

Yumi have already taken the adult chewable vitamin market by storm and more recently turned their attention to the canine health market.

The first thing to say about Yumi Dogs, is that in testing, we found their range of tasty chews to be extremely palatable. Ultimately, this means that there will be no more attempts at hiding tablets in cheese or trying to disguise them in ham!

Packed full with prebiotics and probiotics that have been proven to prevent digestive problems and maintain bowel regularity in dogs.

Theses chews are formulated with chicory root to help soften your dog's stools to relieve constipation, yeast to help good bacteria thrive and Enterococcus Faecium to alleviate intestinal inflammation.

Is there anything I should look out for when I first add a probiotic to my dog's diet?

Like any dietary change, adding a probiotic supplement can occasionally cause a mild digestive upset. If necessary, stop the supplement, let the digestive system settle down and reintroduce again, starting at a very low amount and gradually building up to the label amount.

Is yogurt a prebiotic for dogs?

Yogurt is high in both calcium and protein. It also can act as a probiotic, which can be good for your dog's digestive system. If you feed your dog yogurt, we'd suggest choosing one which is plain and free of any added sweeteners.

How long does it take for prebiotics to work in dogs?

Probiotics and prebiotics won't be an overnight cure for your dog's digestive problems. To rebuild the gut flora, the benefits of a balanced gut microbiome will take time. The products featured in our article will take several days to a couple of weeks of daily use before you can gauge if they're helping your dog.
