Dogs have bad teeth.
It costs owners billions.
Dental disease is the #1 diagnosed condition in dogs — yet almost no dog tolerates brushing.
Dental disease is the #1 diagnosed condition in dogs.
Owners and dogs said yes.
We took CaniBrush to a dog bar event with 200+ dog owners — and the response was overwhelming.

A brush dogs will ask for.
Three innovations that make the impossible possible — brushing that dogs actually enjoy.
Peanut-Butter Flavor
Peanut-butter-infused food-grade nylon bristles make brushing feel like a treat, not a chore. Dogs come to you.
Ultrasonic Vibrating Bristles
Piezoelectric transducers deliver gentle ultrasonic vibrations that break up plaque more effectively than manual brushing.
Flexible Glove Design
Brushing feels like petting. The glove is coated in food-grade rubber — highly water resistant and easy to wipe clean after every session.
Built by hand. Backed by science.
Four simple steps to clean teeth — without the struggle.
Slip on the glove
Fits most adult hand sizes. Snug and comfortable, with a food-grade rubber coating.
Let your dog lick the bristles
They smell peanut butter. They come to you. Let them get comfortable.
Gently brush while petting
Ultrasonic vibrations do the heavy lifting. Brushing feels like petting — your dog barely notices.
Rinse & repeat
Wipe clean with a damp cloth. USB-C rechargeable. Ready for tomorrow's session in minutes.

Why current brushes fail.
No existing product offers proper cleaning AND tolerance. CaniBrush is the first to combine both.
| Product | Dog Tolerance | Cleaning Effectiveness | Verdict |
|---|---|---|---|
| Manual Dog Toothbrush | Low | Moderate | ✗ Most dogs refuse |
| Finger Brush (Jasper 360°) | Moderate | Low | ✗ Still manual effort |
| Dental Chew (Greenies) | High | ~14% plaque only | ~ Tolerance, not cleaning |
| CaniBrush | High | High | ★ MY DOG APPROVES |

Frequently asked questions.
We're finalizing manufacturing now. Waitlist members will be first to know when units are ready. Expected launch: Q4 2026.
Absolutely. Our piezoelectric transducers operate at frequencies proven safe and effective for oral care. The bristles are food-grade nylon — the same material used in high-end children's toothbrushes.
Peanut butter! The bristles are food-grade nylon infused with peanut-butter flavor. Replacement heads will be available.
CaniBrush charges via USB-C. The 3.7V Li-ion battery pack is built into the wrist area of the glove.
The glove is coated in food-grade rubber and is highly water resistant — simply wipe it down with a damp cloth after each use. Do not put it in the washing machine or dishwasher.
None at all. Joining the waitlist is completely free. We'll email you when CaniBrush is available — you decide then whether you want one.
