PetSignal Is Now CANIQO: Here's Why We Changed the Name

A day and a half ago, I changed the name of this product. Not because I wanted to. Because I had to — and because once I understood why, I moved as fast as I could.

Here's the real story.

What Happened

When I launched PetSignal, I did what most early-stage founders do: I searched for the name online, didn't find any obvious conflicts, and moved forward. What I didn't account for was common law trademark ownership — the legal principle that says whoever uses a name first in commerce owns it, whether or not they ever filed a trademark.

A lawyer flagged two other companies already using the PetSignal name. Neither had filed with the USPTO. But under common law, it didn't matter. They got there first.

The right move was clear: rename, and do it quickly.

Why CANIQO

I spent time on this. The name needed to be clean — no trademark conflicts, no competing brands, no ambiguity. It needed to signal dogs without boxing the product into a corner. And it needed to feel like a brand that could grow.

CANIQO — pronounced Can-EE-koh — comes from canine. It has zero USPTO filings against it, zero competing brands on Google, and a domain I was able to secure. It's invented, which gives it the highest level of trademark distinctiveness. And it's timeless — no slang, no trend-chasing, no species lock-in if the product ever expands.

I went from decision to fully rebranded in under 48 hours. New domain live. Email verified. Blog migrated. Directory listings updated. Every touchpoint updated.

What This Means for You

If you're an existing user: nothing changes for you. Your account, your scans, your health data, your history — all of it is intact. The app works exactly the same way. You're just logging into CANIQO now instead of PetSignal.

The mission hasn't changed either. CANIQO analyzes photos of your dog to detect visible health signals, tracks changes over time, and helps you decide when it's worth a call to your vet. We complement veterinary care — we don't replace it. That's not a disclaimer. It's the whole point.

What's Actually Better

Honestly? The name is better.

PetSignal was descriptive. CANIQO is ownable. There's no one else using it, no one competing for the SERP, no confusion about what it is. From a brand-building standpoint, starting with a clean name is one of the most valuable things a young product can have.

I built this because I kept asking myself the same question every time one of my dogs seemed off: is this something, or am I overthinking it? That question is still the one CANIQO is built to answer. The name changed. The problem we're solving didn't.

One More Thing

If you find yourself wondering whether something looks different about your dog — their coat, their eyes, the way they're moving — that's worth paying attention to. Not with panic. With data.

If you haven't tried the new Caniqo yet, now's a good time. No account needed — just upload a photo of your dog and see what the AI picks up.
