Viralatômetro

Find out how much your dog represents the Original Brazilian Mutt!

Have you ever wondered how much of a mixed-breed your dog is?

Viralatômetro is petgenoma's exclusive scientific game, combining fun and genetics to reveal how close your pet's DNA is to the Original Brazilian Mutt.

Based on a genetic database with thousands of mixed-breed dogs analyzed over time, Viralatômetro compares your dog's genetic makeup and shows whether it's among the most authentic representatives of our beloved mixed-breeds.

How do we find the
Original Brazilian Mutt?

The Original Brazilian Mutt is defined from the breeds most frequently found in the genetic makeup of the mixed-breed dogs analyzed by petgenoma.

We identified the 10 breeds that most often appear in the mix of Brazilian mixed-breed dogs — but this may change!

Our database is alive and constantly growing: the more dogs that take part, the more accurate and fun this discovery becomes.

If your pet's DNA has all the breeds present in this average composition, it will be crowned the Original Brazilian Mutt!

Evolution and Ranking

We have already analyzed over 3,000 mixed-breed dogs. But the story is still being written, and the ranking of the most common breeds can change every month. Follow the Viralatômetro updates and see if your pet climbs the podium of the Original Brazilian Mutt.

By taking petgenoma's genetic test, you look after your dog's health while also having fun finding out how much it resembles the Original Brazilian Mutt.
