Honest question: when did you last actually read the back of your dog's toothpaste? We did. And what we found sent us down a rabbit hole that ended with pineapple enzymes. Stick with us.
What is Bromelain?
It's an enzyme. Specifically, a protease, a type of enzyme that breaks down proteins. It lives naturally in the stem and fruit of pineapple (Ananas comosus), and it's been there for a very long time. We just hadn't thought to put it in dog toothpaste until recently.
Here's why it matters for teeth: dental plaque isn't just "dirt." It's a sticky biofilm made mostly of protein-producing bacteria. Which means an enzyme that breaks down proteins is, in theory, exactly what you'd want going after it. Not scraping it. Not covering it with mint. Actually taking it apart.
That's bromelain. Cold-pressed from pineapple, kept in its active form — no processing that strips out what makes it work.
"We kept asking: why does every dog toothpaste smell like bubblegum and do roughly nothing? Bromelain was the answer we kept coming back to."
It's not new. Like, at all.
Indigenous communities across South and Central America were using pineapple medicinally for centuries before Western science showed up and started writing papers about it. They used it for wounds, for digestion, for swelling. They didn't know the word "enzyme." They just knew it worked.
Scientists formally isolated bromelain in the late 1800s. By the mid-20th century, it was showing up in pharmaceutical research, food science, and cosmetics. It's not a trend. It's not something a startup discovered. It's an ingredient that has quietly been proving itself for a very long time, which, honestly, is what made us trust it.
What's actually happening when you brush
This is the part that made us go "oh, okay, that's interesting." Because two things are happening at once, and most toothpastes only do one of them.

🦠 Breaks Down Plaque Biologically |
🪥 Activated by Brushing |
|
Plaque is a sticky biofilm held together by protein bonds. Bromelain cleaves those bonds — dissolving plaque from the inside out, not just scraping the surface. |
The physical motion of brushing activates the enzyme, amplifying its action as you go. Mechanical cleaning and enzymatic breakdown work simultaneously. |
|
🌿 Completely Natural |
🐶 Gentle for Daily Use |
|
Derived entirely from pineapple. No synthetic compounds, no harsh chemicals. Every day your dog brushes, they're getting something genuinely clean. |
Unlike abrasives that can wear enamel over time, bromelain works biochemically. Tough on plaque. Kind to your dog's mouth. |
The bit where bromelain turns out to be an overachiever
We formulated this specifically for oral health. But since we're here, bromelain has been quietly studied for a lot of other things, which either says something about how interesting this enzyme is or how much scientists like pineapple. Possibly both.
DIGESTION As a protease, bromelain helps break down dietary proteins. This is actually why eating pineapple after a big meal isn't just a wives' tale, there's something real happening. For dogs, this is a side note rather than the point, but it's not a bad one.
INFLAMMATION There's a reasonable body of research looking at bromelain's effect on the body's inflammatory response. The findings are still being unpacked. We won't overstate it — but it's there, and it keeps growing.
WOUND CARE Medical-grade bromelain is used in clinical wound debridement. It breaks down damaged tissue without touching the healthy stuff. Which, when you think about it, is a fairly remarkable thing for a fruit enzyme to do.
IMMUNE SUPPORT Some early research points to bromelain interacting with immune function in interesting ways. The science is still forming. Worth watching.
Worth saying: the bromelain in Arca Lab is there for teeth. If you have specific health concerns about your dog, your vet is still the right call, not us.
Why We Use Bromelain in Arca Lab Dog Toothpaste
At Arca Lab, we believe dog dental care should be effective, natural, and something your pup actually enjoys. That's why Bromelain was a non-negotiable for us. 🍍
Most dog toothpastes rely on mild abrasives or simply mask bad breath with flavouring. We wanted something that genuinely works at a deeper level, targeting plaque where it forms, breaking it down biologically, and doing it gently enough for everyday use.
Paired with our watermelon flavour 🍉, Persimmon Fruit Extract for antibacterial gum support, and Vitamin E for soothing protection, Bromelain sits at the heart of a formula built to actually make a difference to your dog's oral health.
Because your dog deserves a toothpaste with a real reason to exist. 🐾
Bromelain: The Takeaway
Nature has a funny way of hiding its best ingredients in plain sight. Bromelain has been sitting inside every pineapple for millions of years, and it turns out it's one of the most effective, gentle, and natural ways to keep your dog's teeth clean.
From ancient medicinal traditions to modern pet dental care, Bromelain's journey is proof that the best ingredients don't need to be invented; sometimes they just need to be discovered. 🍍✨
Whether you're a science nerd who loves knowing exactly what's in your dog's toothpaste, or a pet parent who just wants fresher doggy breath without the drama, Bromelain is the ingredient doing the quiet, brilliant work behind every brush.
Small enzyme. Big results. Happy dog. 🐶🦷

Frequently Asked Questions
What is bromelain, and is it safe for dogs?
Bromelain is a naturally occurring enzyme found in pineapple. It's a protease, meaning it breaks down proteins, which is what makes it effective against plaque. It's been used in food, medicine, and cosmetics for decades. For dogs, it's gentle enough for daily use and doesn't wear down enamel the way abrasive ingredients can over time.
How does bromelain remove plaque from dog teeth?
Plaque is held together by protein bonds. Bromelain breaks those bonds, essentially dismantling the structure of the plaque rather than just scrubbing the surface. When you brush, the motion also activates the enzyme, so the mechanical cleaning and the enzymatic action happen at the same time. Two things at once is a good outcome for something that takes 60 seconds.
Can I use Arca Lab Dog Toothpaste every day?
That's the idea. Daily brushing is what actually makes a difference to dental health, not occasional brushing. Bromelain is gentle enough that daily use isn't a concern, and the watermelon flavour means most dogs don't fight it, which helps with the "doing it every day" part.
What does Arca Lab Dog Toothpaste taste like to dogs?
Watermelon. We tested a few options. Watermelon won. Dogs are opinionated, and we respected that.
Is Arca Lab Dog Toothpaste free from harsh chemicals?
Yes. No synthetic abrasives, no artificial preservatives, no ingredients we wouldn't want to explain. Bromelain is the active ingredient, and it comes from a pineapple, not a lab. The rest of the formula follows the same principle: if it's in there, it's in there for a reason.
