Tendenze nella displasia dell'anca

Razze con oltre 400 esemplari valutati a partire dal 1980 (compreso) confrontati con cani nati negli anni
1987-88 e 1994-95. 
Fonte OFA (Orthopedic Foundation For Animals)

Nota: i dati si riferiscono a soggetti americani e pertanto sono da intendersi solo come "indicativi" dal momento che gli allevatori statunitensi lavorano spesso su linee di sangue diverse dalle nostre e le razze prese in esame non sono necessariamente quelle più diffuse o più allevate in Italia.
