Rated 5 out of 5“Best poop ever!!”
Before adding pre + pro to our packs diet we were dealing with inconsistent pooping in texture and odour … since adding pre + pro we have seen a dramatic change in their poop, it’s always solid and doesn’t stink (as much as poo can smell 🤣)

Rated 5 out of 5“Now, he is much more relaxed”
Alfie used to take a long time to settle and would constantly seek attention or want to play. Now, he is much more relaxed and can peacefully chill without needing to play every second of the evening.

Rated 5 out of 5“The difference has been life changing”
Since introducing CALM+CHILL into his routine, we’ve noticed such a positive change in his ability to switch off and regulate himself. He seems calmer, more settled and much better able to manage all those big Staffy emotions …

“To see this is backed up by Massey University gives me complete confidence in the high grade product.”
Developed with Massey University
Research first. Then the formula.
We partnered with the Massey University School of Animal Sciences on the design, formulation and testing of BONE+JOINT and CALM+CHILL, and that principle still decides what goes in every tin.
-
Designed
Ingredients and doses chosen with Massey’s animal scientists, starting from the research.
-
Formulated
Refined together into a daily blend that's balanced, nutritious and easy to give.
-
Tested
Trialled with pets to check two things: they happily eat it, and they show a positive improvement while they’re on it.
AutoShip

Our story
Made for Chuck. Now for your dog too.
Chuck, one of my miniature dachshunds, has been through four IVDD surgeries. I couldn't find supplements I trusted to support him, so I started Tandem to make them.
Every blend is still made the way I’d want it for my own dogs: researched properly, made in New Zealand, and something they actually want to eat.

Questions
How long until I see a difference?
It depends on the blend and on your dog. Supplements work best with consistent daily use, so give it a few weeks before judging. Each product page has a guide for that blend.
My dog is fussy. Will they eat it?
Most dogs happily eat our blends sprinkled over their usual meal. Start with a small amount and build up over a few days, and if it's not right for your dog, we'll refund you in full.
How much do I give, and how?
Sprinkle it over your dog's usual food once a day. The right amount depends on your dog's weight. The serving guide is on each product page and on the tin.
Can I give more than one blend?
Yes, lots of our customers combine blends. If your dog has a health condition or is on medication, check with your vet before adding anything new.
