Add your dog, and see the family tree its breeds make

Nothing you give us is kept.

Pictures — of the dog, of the report, or both

Add these as well as anything you typed, not instead of it. A report picture is read for the percentages on it; a picture of the dog only ever proposes breeds.

What happens to what you give us

Words stay here. A report is read line by line, and a description is read for the breeds it names — all on our own server, with no AI and nobody else’s service.

Pictures do not. A picture goes to a machine reader off this site, and so does anything those first two readings cannot settle on their own.

You get the last word. Each thing you give us is read for what only it can say: a report for its percentages, a picture of the dog for the breeds it suggests, your own words for which parent they came from. We show you what we made of it beside the tree it draws, and you can change any of it and draw it again.

If you gave us a photo or just what you remember, the breeds are a guess — only percentages from a lab report are measured. The chart says which, breed by breed.

How the chart is built, and what the library holds

The chart this builds is inferred from what you give us, not looked up: it shows an arrangement of eight ancestors that reproduces those breeds and shares, and never a pedigree anyone traced.

We divide the dog into eight great-grandparents, work out what each would have to have been, and fill the slots from the painted breed library — the same way every time. Every portrait is an AI-generated illustration of a breed, not a photograph.

The library holds 274 breeds and a painting of each, but only a few dozen of the blends they make. It is built on a research panel, so a breed on your report may not be on it at all — the form says so rather than guess.

A drawing, not a test result. Pawstrata is not a genetic test, and it does not sell one.

A photo or your memory buys a guess. If you gave us a photo or just what you remember, the breeds are a guess — only percentages from a lab report are measured. The chart says which, breed by breed.

A guessed breed is one we proposed. We propose it after reading your photograph, your words, or both, and the percentage attached to it is ours — not something measured about your dog.

Send us everything you have, in one pass. Give us all of it at once if you have it — a report, a picture, and what you know in your own words.

A ring needs a match. A ring holds a picture only where we have a painting that matches its name. Where we do not, it holds an empty plate: the ring is drawn, the name is printed, and the picture is the part we do not have.

Unpainted mixes stay empty. An ancestor whose name says a mix gets an empty plate too, while that mix goes unpainted — the alternative would be a purebred portrait of its strongest breed, and that is a picture of a different dog.

Two plates, one reason. Two more ancestors get an empty plate for the same reason: their names give the library no breed to draw — an ancestor labelled Mixed names no breed at all, and a breed holding less than a tenth of an ancestor is too little of it to draw.

Their percentages still print. Their percentages can still list those breeds: the name is our estimate of the ancestor, and the percentages are the arithmetic behind it.

One picture stands in. An ancestor that is more than half one breed, with the rest unresolved, shows that breed’s own portrait, set a little inside its ring so you can see it is standing in for an ancestor who was only mostly that breed. At half or less, even that is too much to claim, and the plate stays empty.

You may choose the picture yourself. A person may fill any circle with a painting they chose from the library or with a photograph they supplied. That picture is their choice, not an answer the library found for the ancestor, and a photograph shows the known dog in that circle rather than an inferred likeness.

Your dog’s own plate is different. The dog’s own plate at the foot of the chart is not one of those library-filled rings. Unless you put a picture there, it carries the name instead: nobody has painted your dog, the library only draws kinds of dog, and a portrait of the breed you are mostly would be a picture of a different animal under your dog’s name. Nothing in that circle is chosen for you; the chart supplies the full estimate, and the picture is yours to supply.
