Most dogs are mixes — and that’s the point
Breed information helps Petus suggest health traits to discuss with your vet. For a mixed dog, a DNA report can provide a more detailed breed breakdown.
What makes it different
Built for the job
An image classifier covering 357 dog breeds.
Breed-matched health watch-list
The result feeds a watch-list of the conditions that type of dog is prone to, so you know what to keep an eye on for the rest of their life.
Knows when it is not a dog
Petus checks first and tells you kindly, rather than confidently calling your cat a Chihuahua.
Pairs with a DNA test
Want certainty on a mix? Import a DNA result and Petus blends every breed in it into one lifelong watch-list.
Have a DNA report?
Upload your dog’s DNA report to save the breed percentages and reported genetic markers in their record.

Common questions
- How accurate is the Petus breed identifier?
- The model compares photos with 357 breeds. Results depend on the photo and are less reliable for mixed breeds; they do not establish ancestry.
- Does it work on mixed-breed dogs?
- Yes — most dogs are mixes, and that is the point. The breeds it sees in your dog become a tailored, breed-matched health watch-list. If you want the real breakdown, import a DNA test and Petus blends every breed in the result into one lifelong watch-list.
- Is the breed identifier free?
- Yes. Upload a photo and get a breed result free — no card required.
- What happens if I upload a photo of a cat?
- Petus checks whether the photo is a dog first. If it is not, it tells you kindly rather than confidently calling your cat a Chihuahua.
