Meet Arca Lab: The Australian Dog Toothpaste Born in a Home Garage
If you've ever tried to brush your dog's teeth only to be met with squirming, side-eye, and a dramatic exit, you're not alone. You are exactly who Tommy had in mind when he launched Arca Lab, Australia's newest dog dental care brand.
With the launch of Watermelon Burst, an enzymatic dog toothpaste that's as fruity as it sounds, Arca Lab is on a mission to make daily brushing something dogs actually look forward to. And it all began in a home garage, with two very opinionated dogs.
The Story: Two Dogs, One Problem, and a Lot of Testing
Cherry and Bun were the unlikely co-founders of Arca Lab. Cherry is a Mini Dachshund with strong introverted tendencies. Bun is a Pembroke Welsh Corgi with the opposite energy entirely. Together, they were Tommy's crash course in the challenges of dog dental care, because getting either of them to sit still for a toothbrush was, by his own admission, a daily battle.
"Like many dog owners, I wanted to stay on top of their dental health without turning brushing into a stressful experience," Tommy explains. "If you've ever tried to brush a dog's teeth while they twist away or look at you like you've completely betrayed them, you'll understand."
Determined to find a solution, Tommy spent months testing different approaches, trialling formulas with dogs of all shapes and sizes. One thing that struck him early on was the sheer sameness of what was already on the market. "Every dog toothpaste was some version of beef, chicken, or pork," he says. "You'd spend two minutes brushing their teeth and their breath would just smell like dinner. That's not exactly the fresh, clean result you were hoping for."
The breakthrough came when he leaned into fruit instead. Fruity toothpastes made brushing noticeably more positive, and computationally, left dogs' breath smelling genuinely fresh rather than like their last meal. Time after time across his testing, watermelon came out as the clear favourite. Dogs loved it, and the result was exactly what Tommy had been after: a toothpaste that made dogs want to open their mouths and actually left them smelling like it had done the job.
What started as a fix for two stubborn dogs at home is now a proudly Australian-owned and operated brand, built for every dog parent who knows the dental health struggle is real.
Watermelon Burst: What Makes It Different
Watermelon Burst isn't just a novelty flavour slapped on a standard formula. The toothpaste is built around Bromelain, a natural enzyme derived from pineapple that works at a biological level to help break down the protein bonds holding dental plaque together, rather than simply masking the problem.
Supporting the Bromelain are two additional active ingredients: Persimmon Extract (Diospyros Kaki Fruit Extract), which supports oral freshness and gum balance, and Vitamin E (Tocopheryl Acetate), which helps protect gum tissue and provides antioxidant support.
The formula is also free from a long list of ingredients you don't want near your dog's mouth: no artificial colours, no sulphates (SLS or SLES), no parabens, no silica, no triclosan, and no gluten. It's non-foaming and completely vegan, making it suitable for all dog breeds and sizes.
Every order of Watermelon Burst also includes a complimentary toothbrush, so you can start your dog's dental routine from day one without needing to source anything extra.
It's also worth considering the cost comparison. The average pack of dental sticks retails around $18.95 for 7, which works out to roughly $2.70 per stick. Used daily, that's close to $19 a week, around $82 a month, and nearly $985 a year!
A single bottle of Watermelon Burst at $32.00 covers months of daily brushing, making toothpaste a significantly more economical way to stay on top of your dog's dental health without the ongoing per-use cost.
On the sustainability front, the airless pump bottle, label, and cap are all made from polypropylene (PP [5]), which is accepted in most kerbside recycling bins across Australia, including in NSW. Arca Lab also provides a detailed recycling guide on their website, walking customers through exactly what can and can't be recycled from the packaging.
And when it comes to giving back, Arca Lab has baked purpose directly into every purchase. 1% of every order is donated to a dog welfare non-profit of your choice, selected at checkout, at no extra cost to you. Customers can direct their contribution to one of four partner organisations: Guide Dogs Australia (empowering independence), SMART Animal Sanctuary & Rehoming Centre (finding loving homes), Dog Rescue Newcastle (rescuing the abandoned), or Project Underdog Rescue (providing vital care to help dogs thrive).
As Tommy puts it: "Every bottle of toothpaste you buy helps another dog in need. Now that's something to smile about."
Tommy's Top Tips: How to Build a Daily Brushing Routine That Actually Sticks
Having worked through the learning curve with Cherry and Bun first-hand, Tommy has a few practical tips for dog parents just getting started:
1. Let them taste it first. Before the brush goes anywhere near your dog's teeth, let them sniff and lick the toothpaste on their own terms. A flavour they genuinely enjoy, like watermelon, makes this first step much easier.
2. Find a position that works for both of you. Comfort matters. Choose a relaxed spot where you can easily reach your dog's mouth without either of you feeling stressed or crowded.
3. Start small and use gentle, circular motions. Focus on the outside of the teeth first, working in small circles and paying extra attention to the gum line, where plaque and tartar tend to build up most.
4. Don't chase perfection, chase consistency. "It won't be perfect the first time, and that's completely fine," says Tommy. "Daily consistency is far more valuable than perfect technique, especially when you're just starting out."
5. Always end on a positive note. Offer fresh water after each session, then follow up with plenty of praise or their favourite treat. Making brush time feel like a reward rather than a chore is what turns it from a daily battle into a daily routine.
Meet Arca Lab in Person
Arca Lab has recently been out and about at events, most recently at the Street Paws Festival, where the response from dog owners was overwhelming. Hundreds of curious pups and their humans stopped by the stall to give Watermelon Burst a try, and let's just say the dogs did most of the convincing.
If you'd like to experience it for yourself, Arca Lab will be returning as a stallholder at upcoming local events. It's the perfect opportunity to meet the team, watch your dog react to the toothpaste in real time, and ask any questions you have about getting started with a brushing routine.
Keep an eye on their Instagram @arcalab_ for upcoming event announcements and dates.
