Breed identifier from one photo
Upload a photo and find out what your dog is — identified by a vision model built for the job, not a chatbot guess. Then see what that breed means for their health.
A real classifier, not a language-model guess
The breed identifier is a dedicated image model trained on 120 dog breeds. It picks the right breed first around 90% of the time, and the right breed is in its top five about 99% of the time. That matters because a chatbot describing a photo is guessing from words; a purpose-built classifier is reading the dog. You can try it right now on the free breed check — one photo, a few seconds, a straight answer.

Most dogs are mixes — and that's the point
Knowing your dog is mostly Border Collie isn't trivia. The breed you get back is the doorway to a tailored, breed-matched health watch-list: the conditions that type of dog is prone to, the early signs worth noticing, and the things worth mentioning at the next check-up. Instead of generic dog advice, you get advice shaped to the dog in front of you.
What makes it different
Built for the job
A dedicated vision model trained on 120 breeds — around 90% top-1 accuracy, and the right breed in its top five about 99% of the time.
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.
Want certainty? Add a DNA test
A photo is the fastest way to a good answer, but for a heavily mixed dog it can only take you so far. If you've done a dog DNA test — or you're thinking about one — Petus imports the result and blends every breed in the breakdown into a single watch-list that follows your dog for life. The photo gets you started in seconds; the DNA import makes it precise.

Common questions
How accurate is the Petus breed identifier?
The model is trained on 120 dog breeds. It picks the right breed first around 90% of the time, and the right breed is in its top five about 99% of the time. For heavily mixed dogs, treat the result as a strong hint rather than a verdict.
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.
