What you are taking on
Nobody has written this side yet. It is a judgement rather than data, so it waits for a person — not for a missing source.
Drawn from sources rather than written as an opinion — cited health research, the registry’s own standard, and peer-reviewed longevity. FCI breed standard. One breeder’s animals can differ from any of it, and an empty column means we hold nothing for that side rather than that there is nothing to say.

What to ask for in a Tosa
No breed-specific health panel has been written up for the Tosa on this platform yet. That is a gap in our records, not a clean bill of health — ask the breeder which hereditary conditions their lines are tested for, and ask to see the results for both parents, dated and from a named laboratory.
