Blockchain: A Use Case for Pet Care

It’s a dog’s world. Let’s face it—pets have enjoyed a unique relationship with their human owners as no other animal ever has. From the beginning of time, people around the globe have had relationships with their pets. Today—it’s not uncommon to see restaurants provide pet watering bowls for their customer’s convenience, or to see travelers take their pets with them on a flight from Los Angeles to New York.

Now—blockchain developers and projects have turned their attention on protecting pets. From a pet’s medical history to tracking a wandering dog, blockchain has the promise to help pet owners protect their pets.

Blockchain Use Cases for Pet Owners

The following is a review of two blockchain projects pet owners will be able to use to enhance the ability to better care for their pets. And, for which breeders can use to validate the integrity and authenticity of a breeds pedigree.

PetChain is a web application that tracks data on a blockchain ledger. It allows anyone to review a dog’s data as a “series of timestamped events stored in the blockchain.”

Data can include a record of vaccinations, the pet’s birth date, or used to track a lost pet. It can also include data on a pet’s medical history, previous homes, and more. The ledger stored data provides valuable information to assist veterinarians with diagnosing and treating a pet with easy access to the entire medical record.

Moreover, in the event a dog wanders away and gets lost—when the pet is found, a “chip can be scanned and used to trace back the contact information for the owner by anyone with internet access.” As an added benefit of PetChain is the ability to use blockchain to help a strayed pet in a shelter find a new home. The stored data can help a potential new owner have more information to help them make a decision.

CogniPet Toshendra Kumar Sharma reviewed CogniPet for Blockchain Counsel.

CogniPet is a blockchain based platform that helps a pet owner track their pets, and breeders with documenting a pedigree’s history and with their certificate of ownership. Leveraging blockchain technology, the platform employs an AI image recognition feature to establish an online link. This can easily help pet owners trace their pets. Moreover, pet owners can create an “interactive animal timeline” which can be shared with family and friends.

Currently, CogniPet is developing an app to assist pet owners arrange photos to assist the owner with finding a lost pet. It allows owners to collate data on their pet, and then store the data and photos on the blockchain. In a similar way as facial recognition software can be used to identify a person—so too will the image recognition feature be useful in tracing a lost pet “as the system will search the database for the photos of the missing pet.”

Breeders will benefit with CogniPet by being able to use blockchain to trace all relevant breeding data. It allows breeders to collate and store data and photos of the pedigree animal on blockchain.

For anyone interested in researching the animal, all the data will be accurately and immutability stored on the blockchain that includes the “location and time stamp”. All the data is “secured using cryptography”. This digital documentation represents an “ideal replacement for paper documents as it forms a digital certificate”.

The system facilitates a well-documented ownership transfer from breeder to the new owner. And it can be used for a subsequent sale or transfer, should the need arise. The digital certificate serves as the certificate of ownership. After the sale is made, it can provide the timeline ID as proof and transfer it to the buyer.


We love our pets and welcome them as family members. Breeders are in the business of breeding pedigree animals—often entering their animals in pet shows. Blockchain is a technology that can be applied to help pet owners and breeders better care for their pets.

Blockchain has the ability to share a pet’s information. “From an animal’s breeding history to its yearly veterinary care, health records, dog show awards, training certifications,” says Aidan Connolly—blockchain can store data from any device, robots, sensors or microchips.
