From Our Founder
Tandem was born out of my unwavering commitment to providing the very best for my three miniature dachshunds, Chuck, Darcy, and Edison. As I grappled with the challenges of finding effective, proven, and high-quality supplements to support Chuck during his recovery from four IVDD surgeries and to prevent further recurrences, I realised that a solution was missing in the market.

My 3 have been on the PRE+PRO Powder for just over a week. The difference is how much poop.is produced is incredible. I would have to scoop poop at least once a day amd have several to collect. Today I hadn't cleaned up.in 2 days and had 3 poops around the property ro clean up!
Also have noticed fresher breath. This will be a daily staple from now on!

Pepper has been on this product for a matter of days and we are already noticing a huge difference! Having been on medications after major surgery, her tummy has been very upset. We’re back to seeing healthy poops and an even happier Pepper!

We had the privilege of taste testing Pre+Pro over the last 4 months and we are absolutely loving the results! We first started Pre+Pro in Summer which is when Hunter’s allergies are normally at their worst. I was able to cut his antihistamines down to once a day instead of twice a day now and I feel like he’s not needing soaks as much and hasn’t been needing cream or balm on his paws every night anymore which we are both pleased about. His paws aren’t looking so red as often as they were and haven’t gotten as bad as they did last year. Truly thankful for this product it has noticeable improved Hunter’s skin and coat. There are so many benefits! I haven’t had to clean his ears often either since he has been on Pre+Pro. His stools have also improved a lot too which is definitely a win. Hunter loves Pre+Pro with warm water and Tandem Deer milk with his kibble for breakfast (prefect winter combo to warm up little bellies)

This stuff has been truly amazing! Better stools, less itchy belly and paws! I couldn’t have asked for more 🤩 Highly recommend this product!

Frost has been using the Tandem PRE+PRO powder for a few weeks now, and the difference is noticeable – he's maintaining weight more consistently and looks more toned and muscular overall with the boost to his gut.
It’s great knowing these are supporting his health from the inside out – a simple addition to his routine that's clearly having a positive impact on his health.

I’ve been using Tandem’s PRE+PRO for dogs for a few months now, and the results have been outstanding. Since starting PRE+PRO, her bowel movements have become much smaller and more regular.
Her poops are noticeably smaller and easier to pick up — a sign that her body is absorbing nutrients more efficiently. Her breath has also improved dramatically (huge plus for cuddle time), and I’ve noticed her ears stay much cleaner than they used to. I rarely have to clean them nowadays, if ever.
Overall, it’s clear that Tandem’s formula is doing something right from the inside out. I love knowing I’m supporting her gut health and her whole body with something that actually works.
Highly recommend for any dog parent looking to improve their pup’s digestion and overall wellness!
I’ve been trialling this PRE+PRO supplement for a while now, and the difference in both of my dogs has been incredible.
Bentley has always had a very sensitive tummy. We’ve dealt with frequent gastro upsets, unpredictable poops, and a lot of trial and error with food. Since starting PRE+PRO, his digestion has really started to settle. His poops are becoming much more regular and consistent, and he just seems more comfortable overall.
Cooper suffers from atopic dermatitis and severe grass irritation. His legs and paws were often red, raw, incredibly itchy, and so sore. It was heartbreaking watching him constantly lick and scratch at them. Since being on the probiotic, I’ve noticed a big improvement. His skin is looking a lot less angry, and the excessive licking and itching have dramatically reduced. He just seems so much more comfortable in his skin now, literally.
PRE+PRO has become a staple in our daily routine. It’s made a real difference in both my dogs’ health, from the inside out. If you have pups with sensitive tummies or skin issues, I can’t recommend this enough that you give it a go!

We’ve been lucky enough to test the Tandem PRE+PRO with Zeus and Rhea. Zeus has always been susceptible to skin irritations and food sensitivities. The PRE+PRO has helped so much with settling Zeus’s gut if he manages to sneak a treat when out on walks. His paws and stomach don’t get as red when frolicking in the long green grass.
Both Zeus and Rhea have loved the addition of PRE+PRO mixed into their breakfasts. It’s nice to know they are getting the extra help they need to feel ready for their adventures. Their breath has also been fresher, which is nice when they are on a seafood-based diet.

This is a really thought-out product, which made the choice to try Harlo on it easier as she suffers from intestinal and gut issues.
Using PRE+PRO has been a big support in her ongoing recovery.
We found after 3 weeks her ears were less gunky (commented on by our vet), and her sometimes stinky breath had gone.
Just after a month in, her stools started decreasing in size by half which tells me she's absorbing the good stuff from her food again!
We constantly get compliments about her shiny coat, too.
If you are looking for a great all-round supplement, one that aids healing and has preventative support.. this is it.
We started our Tandem PRE+PRO journey gently — just 1 scoop a day, building up slowly over a week. Lucy hoovered it like a seasoned pro, while Lenny gave me the side-eye and acted personally victimised by a sprinkle of pumpkin. Apparently, “not a vegetarian” is his excuse 🙄. But after a month of sneaky servings and stubborn negotiations, he’s now on full daily doses with no complaints (and maybe even a bit of tail wagging).
We’ve been using it since December 2024, and honestly? The results are speaking louder than Lenny’s opinions at the vet.

🩷 What We’ve Noticed
💨 Fresher Breath
Now this is a win… with an asterisk. When Lucy isn’t indulging in her favourite “poo snack” (yes, we all have our flaws), her breath is noticeably fresher. Not minty, but no longer the kind that could take the paint off the walls. So we’ll take that as a solid improvement!
🐾 Less Itching + Yeast Drama
One of the biggest reasons we wanted to trial PRE+PRO was Lucy’s yeasty ears and itchy skin — especially flaring after eating dog roll. May was full of dog shows, and I may have gotten a bit carried away with high-value bribes (aka: the dreaded roll). But since we’ve ditched it again and kept PRE+PRO in the mix, her skin has settled beautifully and her ears? Back to behaving.
👂 Happier, Cleaner Ears
We used to have to clean Lucy’s ears weekly just to stay ahead of the game. Now? It’s monthly at most — or when I’ve gone rogue with the dog roll again. The reduction in ear gunk and flare-ups is clear as day, and I’m very much enjoying not wrestling her every Sunday with an ear wash bottle.
💩 Smaller, More Predictable Poos
You can definitely tell when it’s been missed — their stools lose that neat, golden consistency and start doing their own thing. But with PRE+PRO in the bowl? Firm, tidy, and textbook perfect. Honestly, it’s the kind of result you don’t realise you appreciate until it’s gone.
💨 Less Gas or Tummy Upset
They’re raw-fed, so we don’t get much gas to begin with — but even when I’ve overdone it on dog roll, their tummies have stayed pretty calm. Which is saying something, because Lenny once acted like a single boiled egg ended his entire digestive trust.
⸻
🎁 Final Thoughts
I love the packaging (chonky & cute – very on brand), it’s easy to use, and more importantly — it works. From yeast to ears to poos, the changes in Lucy have been obvious, and even Lenny has warmed up to it.
Would I recommend it? Absolutely. It’s given me the confidence to let Lucy enjoy her dog roll occasionally at shows, without sending her ears into meltdown. It’s been a real gut-level glow-up.
And yes – we’ll absolutely keep using it post-trial. Our food routine now comes with a side of PRE+PRO. The dogs gut health demand it. 🐾🫶

We’ve been using PRE+PRO with our 4 dogs for about 6 months now, and honestly — the difference has been amazing!
First up… the poops! 💩 We noticed almost straight away that they were smaller, more consistent, and way easier to clean up. Upset tummies used to be a regular thing around here — now they’re super rare.
Two of our dogs have short coats and used to suffer from seasonal itchy skin. These days? Barely a scratch in sight.
And our puppy, who had a history of ear infections when we brought him home? Not a single one since starting on these probiotics.
It's a solid 5 stars from us ⭐⭐⭐⭐⭐ — I recommend it to every dog owner. There really is something in it for every dog, and we've seen the results firsthand.

Duke is an 11-year-old lab x springer spaniel who has been using the PRE+PRO for almost three months now. I contacted Tandem because we were having problems with his ears smelling, and the vet said we needed to clean them regularly. They were very hard to clean, and he didn’t particularly like us touching them. They were “dusty” and inflamed inside—think dusty like he was shedding lots of skin.
He also often itched his ears. We have definitely noticed a difference in him. He doesn’t mind us touching his ears, and they don’t smell as bad as they did. They are not dusty inside anymore, and they look less inflamed. I don’t think I see him itching his ears at all anymore, so he obviously feels better.
Hoping these things continue to get even better in time as well.
Also, a very happy and unexpected bonus for us is that his breath isn’t as horrible as it used to be!
Thank you, Tandem Pet!

Our older dog likes the taste of the powder and eats her food with it sprinkled on top. A bonus as she is hard to give tablets to. It has helped with her mobility and joint health.

Fantastic product. Our golden retriever puppy loves it sprinkled on her food. Will buy again.

Such Amazing service! The team went above and beyond to ship my package after the courier pick up by personally dropping it down to the post depot so I could recieve the package overnight for my kitty who has been off her food having IBD and can only eat a novel venison protein diet!! Package arrived the next day! She is very fussy and was instantly so keen on the smell upon opeing the tin and was frantically licking the venison broth powder! She also wolfed her food she was turning her nose up at after mixing it through! Great start with this product so far and can't wait to see my kitty's results!
