Made a massive difference

We have been trialing the BONE+JOINT chews and powder through the manufacturing process with Tandem Pet over the last year.

One of our dogs has had bilateral TPLO surgeries on his knees, and has advanced ***** already in all 4 limbs at the age of 3.

These chews genuinely made a massive difference in his mobility in less than a month. We’ve been able to get back out for daily walks with him, without limping, something I never thought he would be able to do again.

Such a difference in Bentley’s mobility

Palatable for my fussy boys and that’s saying something! These chews make it such a fun and easy way to get supplements in. My older dog, who usually turns his nose up at anything added to his food, now eats these first off the dinner plate every night.

Since starting them, I’ve noticed such a difference in Bentley’s mobility. He’s moving more freely, and visibly more comfortable in his joints.

For my younger pup, Cooper, it’s also the perfect preventative measure to get all the goodness into his diet to help support his bones & joints as he gets older.

Made a meaningful difference

We’ve been trialling Tandem Pet’s BONE+JOINT supplement for just over a year with our two dachshunds, Mila, aged 12 and Minnie, aged 15. Both have had spinal surgery, and Minnie was also diagnosed with immune-mediated bilateral carpal polyarthritis. We were told she’d likely be on steroids for life.

Since starting BONE+JOINT, and with our vet’s guidance, we were able to wean Minnie off steroids completely. Before treatment, she had no use of her front legs; today, she’s moving comfortably and enjoying proper walks again. Mila’s mobility has been consistently good, too, with easier, freer movement day to day. The chews are an easy yes at mealtimes and the powder mixes in without fuss — palatable and simple to stick with long-term.

From our experience, BONE+JOINT has made a meaningful difference to both our girls’ comfort and quality of life.

Pro Probiotic This is a great product well done.

This is a great product, my dogs just look stunning

That’s wonderful to hear! We love knowing PRE+PRO is helping your dogs look and feel their best. Thanks for sharing and being part of our Tandem community.

Difference has been amazing!

We’ve been using the Tandem BONE+JOINT Chews and Powder for our dog Astra, and the difference has been amazing! 💛 She’s been noticeably more comfortable since we started. Her movement is freer, and she’s been getting around with ease, even on her busier days out tracking and adventuring!

I love that these support her joints, cartilage, and bones long-term, helping keep her active and happy. Plus, she absolutely loves them, she goes for her joint chews first at dinner every night! Highly recommend for any dog needing gentle, daily joint support. 🐾

I recommend BONE+JOINT to all my rehab clients

Since starting BONE+JOINT we’ve seen our dog with joint issues move so much easier.

She lives a very active lifestyle on a farm, so it’s important we support her and our other dogs as much as possible to keep their joints as healthy and as mobile as possible as they age.

Since trying it for myself, I recommend BONE+JOINT to all my canine rehab clients, and we wouldn’t be without it in our house.

Definitely notice a difference in his movements.

The Tandem BONE+JOINT chews have been such a huge help for Zeus; he loves the taste of them and thinks they are a treat, which makes taking another supplement a breeze.

Being a high energy dog when out of the house, I know these help support his joints and cartilage for all that bush bashing he does.

Definitely notice a difference in his movements when we have these tasty morsels in his diet.

Another Stellar product from the Tandem team.

I’m quite honestly speechless!

If there was one supplement out there I’d recommend to anyone it would hands down be the BONE+JOINT from Tandem.

After our 8 month old pup was diagnosed with hip dysplasia in Feb of this year we were on the hunt for products to support her joints.

Three orthopaedic surgeries later, Pepper has been trialling the BONE+JOINT powder since March and the difference it has made to her quality of life is incredible.

We are so grateful to have been part of the trial, I wish I had more to say but I’m quite honestly speechless. BONE+JOINT has completely transformed her life for the better, & being gentle enough for long-term use means she’s set up for life ❤️

We love the ease of the chews

Old Man Duke is 11years old. He’s getting slower on his walks and when we are done (before adding BONE+JOINT to his diet - but using another well known product on the market) it was a mission to try get him back into the boot of our car. He’s fine to jump in before a walk but afterwards he was always hesitant because he just didn’t have the belief in his back legs to get him in the car. He would often put his paws up and wait for one of us to lift him in.

We love the ease of the chews, and Duke and his brother love the taste. Now, after a walk, Duke is quite happy to jump back in the boot of the car. That has been our biggest tell that this product really is working for Duke.

Thank you, Tandem pet!

It’s our holy grail

Why Tandem BONE+JOINT?

Because it’s been a game changer for Alfie. Sometimes I forget he even had knee surgery just over a year ago. Ever since we started using the Tandem BONE+JOINT supplement, the number of times Alfie has gone airborne to catch the ball - and landed perfectly fine - is amazing.

We’re all about maintenance and prevention now. Tandem BONE+JOINT helps active Alfie maintain joint structure and flexibility. It contains all the essential supplements, minerals, and nutrients needed for bone density, skeletal strength, and cartilage support.

Not to mention, the research behind this product was done in collaboration with Massey University - so in short? It’s LEGIT.

What’s also been awesome for us is the choice between powder and chew formats, which makes mealtimes more flexible.

We swear by Tandem BONE+JOINT, it’s our holy grail and a total necessity in our household.

This will be a permanent staple in our house!

Sadie Mae is a 4-year-old cavalier with mitral valve disease.

Earlier this year, I noticed she was reluctant to hop on and off the bed and slow going up and down stairs. The vet found crepitus in one of her back knees. Because of her heart it was decided not worth the risk sedating her just for X-ray. The suspicion was a partial meniscus tear. I was advised to start a joint supplement. I started her immediately on the BONE+JOINT supplement. Within days she had improved mobility. At her vet review several weeks later, the vet was pleasantly surprised to find the crepitus had resolved.

The powder is so easy to add to a meal. just sprinkle on top and the chews are great as a daily treat. Sadie loves both and always licks the bowl clean

As a pet guardian, the research done behind this supplement gives me real peace of mind I am using something that is backed up by data. This will be a permanent staple in our house!

Our first tub and already Mavericks ear is clearing up

Our first tub and already Mavericks ear is clearing up. He’s been plagued with a yeasty ear for months but it’s settled down and he’s so much happier!

Go Maverick! Ears can often be one of the first places to show improvement when gut balance starts to restore. Thanks for sharing his story with us!

Good investment

Great changes

Have noticed a change in our dogs coat, ears and mood. Very happy with the results

That’s so great to hear and thank you for sharing! We love knowing your dog’s coat, ears, and even mood have all improved. That’s exactly the kind of whole-body support PRE+PRO was designed for. Give them a big pat from us!

Happy dog, happy mum!

We are using the PRE+PRO for our girl after she was unwell with skin irritations and ear infections and vet visits.

Now she is happy with her change in diet using this supplement on her food. I'm hoping that this continues. Happy dog, happy mum!

We absolutely love hearing this and thank you for sharing! It’s so wonderful to know your girl is feeling happier and healthier again after everything she’s been through.

Give her some extra pats from us. happy dog, happy mum indeed!

Refill for the best pre & pro? YES PLEASE!

Absolutely love the refill option & how easy it is to dispense into my container 😍

Nothing but great!

This product has been nothing but great!

Only been using for a week and already has stopped my dog from shaking his head dramatically constantly.

Initially I was given ear drops from the vet at a cost of $100 for a yeast infection. But as I have a 80 kilogram stubborn St Bernard these were not able to be administered.

My only fault would be not having a measuring scoop supplied.

As my dog is stubborn and spoiled he does require me to mix it with ice cream otherwise he thinks I’m poisoning his food (I did mention he was stubborn).

Already recommended it to other dog owners who experience the same problems.

We’re so happy to hear your St Bernard is already feeling more comfortable after just a week. It sounds like he knows exactly what he likes (ice cream and all!).

We really appreciate you recommending PRE+PRO to other owners.

Give your big boy some extra pats from us, and thank you again for trusting Tandem to support his health!
