01 · The pitch

What is a Dog Gatekeeper?

A Dog Gatekeeper is a Pet Gatekeeper made from your real dog. The Pet Gatekeeper Chrome extension hijacks your screen with your Dog Gatekeeper the moment you've been scrolling a watched site too long — a short, silent video of your dog in the way of your scroll, until your time-out ends.

02 · Why it works

Why people make a dog gatekeeper

Dogs are good at making you stop. They walk into the room, they look at you, you put the phone down. A Dog Gatekeeper is that, on the screen, on demand.

Unlike a notification, your own dog showing up doesn't feel like an interruption — it feels like the part of your day you keep meaning to get to.

03 · Where it earns its keep

Where a Dog Gatekeeper fits your day

The home office.

A Dog Gatekeeper sits well next to a real dog at your feet. The extension nudges you up when you've been three tabs deep too long, and the dog gets the walk that was supposed to happen anyway.

Travel and hotel desks.

A Dog Gatekeeper is the version of your dog you can take with you. Five seconds of your dog blocking your hotel-room scroll is a strangely large amount of comfort.

Heavy meeting days.

Between calls is when the doomscroll sneaks in. A Dog Gatekeeper between meetings stops the slide before it starts. Per-domain rules in the extension keep it out of screenshares.

04 · How it works

How to make your own dog gatekeeper, step by step

01
Pick the right photos
1–4 photos of your dog, ideally with a clear background. Sit / down / loaf poses work well.
02
Upload and confirm pose
We generate two green-screen poses from your photos. Approve the look — or regenerate within the included free retries if you want different poses.
03
Generate two short videos
An intro clip and a loop. Tune the chroma-key live in your browser — long fur and white coats need a touch of edge feathering.
04
Redeem in the extension
Get an 8-character code. Paste it into the extension's redemption screen and your dog is the next thing you see when TikTok tries to keep you.

05 · Tips

Tips for great dog videos

Photos at the dog's eye level read better than top-down phone snaps.
Avoid green or yellow backgrounds — they collide with the chroma-key step.
White and cream dogs benefit from a higher edge-feather setting; the live preview shows it instantly.
Working dogs (collies, shepherds) tend to look intense — softer shots feel friendlier on screen.
