Many of us take daily supplements to make sure we get enough essential nutrients and to improve our overall health.

Whether you reach for vitamin C when you're feeling under the weather or take daily fish oil to improve your joints, there's overwhelming evidence to suggest that supplements can enhance our health in many ways.

So, if supplements can do wonders for us, why wouldn't they do the same for our dogs?

If your dog is healthy and on a complete and balanced diet, they're unlikely to need any supplements because their diet will have everything that they need to thrive.

However, as you know, dogs can suffer from a whole range of health issues including skin & coat problems, anxiety, joint pain and gastrointestinal problems that supplements could help to alleviate.

The UK supplement market is seeing a big shift, with brands like Buddy & Lola, Pawd Drinks, and Pets Purest offering high-quality, natural alternatives.

Our guide is chock full of the best dog health supplements we've tested over the years including joint support, probiotics, and calming solutions to help you make informed choices.

Palatability is key, and we've tested each option but ultimately, you know your dog best. If they aren't fussy then you can probably take advantage of some of the cheaper, tablet solutions. If they can sniff out a tablet hiding at a 1000 yards, then we'd suggest a chew or a liquid.

Let's take a closer look at some of the best natural health supplements available for your dog.

Buying Advice for Dog Supplements

Our Picks of the Best Dog Supplements

1. Joint Care

Pooch & Mutt

Many dogs experience joint pain and stiffness, often due to conditions like arthritis. This discomfort can worsen over time, whether triggered by a past injury or a gradual breakdown.

To help promote healthy joints and potentially prevent future problems, you could consider adding joint supplements to your dog's diet.

If you're looking for dog joint support from a UK company with experience then take a closer look at the new and improved Joint Care tablets from Pooch & Mutt.

These Joint Care tablets offer protection for joints as well as fighting inflammation and stiffness too. They contain several of the most renowned joint supporting ingredients at higher concentrations than many other brands.

It's worth mentioning that these little tablets use 33% more glucosamine and have 6 times higher concentration of hyaluronic acid than some other market leading canine joint pills.

Plus they have MSM which is used for arthritis treatments in humans and can slow the gradual degeneration of your dog's joints and collagen which helps to reduce joint pain.

Pooch & Mutt offer two sizes of tablet so you can buy the best size for your dog.

Let's talk palatability.

Got a picky pup ? Well so have we and these tablets were woofed down like treats !

That's always a concern with tablets that you'll end up desperately trying to hide them in cheese or wet dog food. We were totally amazed at how our usually super picky dog came back for more! Game–changer!

So Pooch & Mutt recommend :

Small Tablets -

1 tablet daily per 5kg body weight ( young/adult dogs)

2 tablets daily per 5kg body weight (senior/ injured dogs)

Large Tablets -

1 tablet daily per 10kg (young/adult dogs)

2 tablets daily per 10kg (senior/injured dogs)

Our Verdict: Overall our favourite dog joint supplement because each tablet is packed full of a combination of the best, higher concentration natural joint-care ingredients and they scored high on the palatability test.

Reasons to Buy

  + Great value option

  + Highly palatable

  + Easy to administer

  + High concentration

Reasons to Avoid

  - If your dog is super picky

2. Calming & Anxiety

Buddy & Lola

Popular brand Buddy & Lola offers a range of natural, high-quality supplements addressing various canine health concerns.

Understanding the struggle of getting picky pups to take supplements, Buddy & Lola offers a tempting selection of powders and chews that would satisfy even a Goldilocks-level picky pup. Both are excellent for promoting long-term calmness without resorting to prescription medications.

Importantly both options are 100% natural calming without the sedatives.

We love the Peaceful Pooch daily chews as they're yummy ( ike treats) so hassle free. In testing we found the powder particularly easy to mix into raw or wet food.

We'd recommend calculating the daily price for your dog's specific weight as the chews or powder may work out cheaper depending on the feeding guidelines.

Be aware that whichever form you chose, Peaceful Pooch needs to be used daily over the course of a few months for you to see a gradual improvement in your dog's emotional balance.

Packed full of 100% natural ingredients to promote relaxation -

💜 Lemon balm which encourages calm behaviour

💜 Passion flower which helps support your dog's dopamine levels

💜 L-Tryptophan a natural occurring amino acids which supports production of serotonin

⭐️ We tested Peaceful Pooch with Otis, an amazing 10 year old Labrador. Whilst Otis is very laid back and chilled most of the time, he was getting anxious and barking at the sound of motorbikes on the busy road outside his house (particularly during the evenings). After a month taking the daily chews he calmed down significantly and although his ears pricked at the sound, he didn't resort to barking.

Buddy & Lola offer a storage tin to help keep those supplements fresh and easy to administer (a game changer for tricky to measure powders). The storage tin is FREE with new subscriptions or available to buy separately with one-off orders.

Ultimately, Buddy & Lola offer some great money saving bundles, so you could buy it alongside their amazing Super Tummy Instant.

They also offer a subscribe and save option, plus free delivery on subscriptions or orders over £30. Better still they offer a 30 day money-back guarantee.

Reasons to Buy

  + Choice of chews or powder

  + Gradual longer term results

  + 100% natural ingredients

  + Money back guarantee

Reasons to Avoid

  - Full benefits take over 30 days

3. General Health

PAWD DRINKS

Sometimes you're looking for an all-rounder, for those dogs that don’t lean towards a particular niggle but you want to maintain their overall health.

We're used to seeing liquid supplements for people, especially children who hate pills, so it's a no-brainer that they'd be great for dogs too.

Here at Smart Bark we're big fans of the PAWD DRINKS range of 100% natural supplements for dogs.

Formulated by top animal nutritionists and vet-approved, PAWD DRINKS Wellness is a comprehensive tonic designed to enhance your dog's overall health.

Their dedication to using wholesome ingredients and their UK-based production makes them a standout choice for us.

The liquid format allows for rapid absorption into your dog's system, and when taken regularly, it delivers long-term benefits such as improved recovery, immune support, and cognitive function.

The liquid format allows for rapid absorption into your dog's system, and when taken regularly, it delivers long-term benefits such as improved recovery, immune support, and cognitive function.

4. Dental

Buddy & Lola

Very few dogs like having their teeth brushed, and some flat-out won’t tolerate it. But teeth and gum disease are “far and away” the most common health problem for dogs.

Whilst nothing can replace teeth brushing as the best method for keeping those gnashers pearly white, there are some great options on the market if teeth brushing simply isn't an option for you.

Buddy & Lola's Pearly Pups is a standout dental care solution, offering a unique powder formula crafted with a powerful blend of natural ingredients.

Seaweed, parsley, turmeric, charcoal, and peppermint work together to combat plaque and doggy breath.

Turmeric's natural abrasiveness aids in cleaning teeth and gums, while activated charcoal whitens by absorbing stains. Finally, parsley and peppermint prevent bacterial buildup, ensuring fresh breath.

Using this powder is a breeze – just sprinkle it on your dog's food! Each pack includes a long-handled spoon? Genius! Our testers loved it because it's super easy to find in the bag

Based on recommended amounts, we found in testing that a pack of Pearly Pups lasted 30 days for a 11-25kg dog.

To make Pearly Pups a regular part of your dog's routine, Buddy & Lola's Subscribe and Save option offers a significant 30% saving.

Oh! and we should mention they also offer a 30 day no fuss money-back guarantee and free delivery with orders over £30.

Reasons to Buy

  + Simply sprinkle on food

  + Multiple active ingredients

  + Tackles plaque and freshens breath

  + Subscribe & Save option

Reasons to Avoid

   - Not as good as teeth brushing

5. Probiotics

Pooch & Mutt

Bionic Biotic is one of Pooch & Mutt's best selling products, so let's take a closer look at why so many dog lovers (including us) swear by it.

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 a dry diet then you can mix the powder with salmon oil or yoghurt before adding to dry food to help it 'stick'.

What really makes Bionic Biotic stand out for us is that the probiotics offer a whole range of benefits -

⭐️ 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 offers dual benefits for your dog's digestive and skin health. Chicory root, a natural fibre source, promotes healthy stools, easing constipation, diarrhoea, and scooting.

Meanwhile, salmon oil, rich in Omega-3s, helps reduce inflammation from allergies and skin irritations.

We found in testing that the 200g sachet lasted a 10 – 25kg dog approximately 1 month.

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

Reasons to Buy

  + Great for digestion issues

  + Natural ingredients

  + Great for stool quality

  + Easy to add to food

Reasons to Avoid

  - If you're looking to treat a specific health issue

6. Skin & Coat

Pets Purest

Adding salmon oil to your dog's day is an easy and cost effective way to help deal with skin and coat irritation.

Renowned for their range of all-natural products, we recommend Pets Purest 100% Salmon Oil because it's full of nutrients, without adding unnecessary fillers and chemicals. This is really important if your dog is sensitive to different foods.

Pet's Purest Salmon Oil is made with ethically sourced, sustainable Scottish salmon. Packed with omega-3 fatty acids, this natural oil is scientifically proven to promote healthy skin and a radiant coat for your furry friend.

It has a wealth of 5 ⭐️ reviews from some very happy dog lovers including our Freddie.

Really easy to use, simply pump the appropriate amount on your dog's meal before serving.

Be aware that some fish oil supplements can go off quickly, so it always pays to keep a close eye on the expiry date. We love that our bottle of Pets Purest Salmon Oil had a really long life - 2 years !

Alternatively you could take a look at Pets Purest range of Daily Supplements. An incredibly easy way to supplement your dog's diet, these bottles come with a no-mess pump to provide a measured dose of active ingredients.

We're big fans of these 'pump and serve' supplements as they're hassle-free.

Their Daily Allergy & Itch contains a blend of botanical herbs and minerals known for their natural antihistamine effects including Scottish salmon oil, skullcap, ginkgo and nettle.

Importantly their Salmon Oil and Daily Allergy & Itch both have a natural, delicious taste that should appeal to the fussiest of dogs - so dog-lovers with picky pups, this could be a great option for you !

Buying Advice for Dog 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 our top tips to bear in mind when you are choosing a supplement for your dog :-

✅ Select an experienced brand

✅ Choose a delivery method that you think will be most palatable for your dog whether that’s tablets, liquid, powder or chews.

✅ We recommend that you talk to your vet about what supplements your dog may need. It’s worth noting that ingredients in some herbal supplements can interact with any existing medication

Lastly, we found that there appears to be an enormous range of prices when looking at supplements for dogs.

When considering pricing, bear in mind the quantity of product purchased (obviously the larger amounts work out cheaper per dose) and the size of your dog as larger breeds will need significantly higher daily doses.

It's definitely worth doing the maths specifically for your dog, before making a decision.

We hope this review helps you make an informed decision about your dog's supplement needs

To your dog's health and happiness
