How the breed identifier works
This is a real vision classifier, purpose-built for the job — not a language model guessing from a description. It was trained on labelled photographs across 120 dog breeds, and in our tests it puts the right breed first around 90% of the time and within its top five around 99% of the time. Photo quality matters: a clear, well-lit shot of the face and body beats a blurry one from across the park.
Before it matches anything, it checks the photo actually contains a dog. If you upload your cat, your sofa, or your lunch, it will say so politely rather than invent a breed.
You always get the top five matches with confidence scores, not just a single name. For mixed-breed dogs that spread is the honest answer: it shows the closest pure breeds the model can see. For the real percentages, a DNA test is the ground truth — and you can import DNA results into Petus to build a watch-list from the actual mix.
Why breed matters for health
Breed is one of the strongest predictors of what will go wrong, and when. Cavaliers are prone to heart disease, Dachshunds to back problems, Labradors to hip dysplasia and weight gain, brachycephalic breeds to airway trouble. Knowing the breed turns vague worry into a short, specific list of things worth watching — and catching most of those conditions early is cheaper and kinder than catching them late.
That is what Petus is built around. Once you know the breed, you can see how breed identification feeds your dog’s health record, and create a free profile so those risks are tracked over your dog’s whole life, not looked up once and forgotten.
One honest caveat: breed risk is a probability, not a diagnosis. Petus gives you a straight answer — nothing, watch it, or see a vet — and when something needs a professional, it says so. It does not replace your vet.
Common questions
Is the breed identifier free?
Yes. Upload a photo and you get the breed match and confidence scores at no cost, with no account needed. If you want the full breed health guide saved and emailed to you, we ask for your email — that part is optional.
Is it accurate for mixed breeds?
For a mixed-breed dog it shows the closest pure breeds it can see, with a confidence score for each. That is a useful visual estimate, but only a DNA test gives the real split. If you have DNA results, you can import them into Petus and we build the health watch-list from the actual breed mix.
What happens to my photo?
Your photo is sent securely, used once to run the breed check, and is not made public or used to advertise to you. If you create a Petus profile you can choose to save photos to your dog’s own health record.
