DogUSign — Your dog's important documents, in one link

The world's first paw print signature platform. Executed by paw. Sealed by snout.

DogUSign uses AI to generate photorealistic ink stamp signatures from photos of your dog's paw and nose. These biometric marks serve as visual identity tools for signing pet service documents, creating shareable digital dog passports, and generating business cards.

Core Features

Two-Factor Paw-thentication™ (2FPA)

A dual-biometric identity system using two AI-generated marks:

Paw Mark — An ink stamp impression generated from a photo of your dog's paw, used for signing documents and business cards.
Snout Mark — A unique visual identifier generated from a photo of your dog's nose, tied to their profile. Dog nose prints are biometrically unique, like human fingerprints.

Dogumentation (Digital Dog Passport)

A comprehensive digital profile for each dog, including vaccination records, vet history, microchip and registration details, insurance information, emergency contacts, care instructions, feeding schedules, walk spots, known commands, socialisation logs, and grooming records. Shareable via link or QR code.

Document Signing

Dogs can "sign" agreements and forms using their generated paw mark signature — including the Good Dog Agreement and custom business forms.

Dogu-Wallet (Digital Cards)

Business card generator featuring your dog's paw mark signature, profile photo, and key details.

Travel Planner

International travel planning wizard with AI-generated checklists, destination-specific requirements, and a specialist directory for pet travel services.

AI Technology
