The Orthopedic Foundation for Animals (OFA) has updated their website to include the most recent statistics for incidence of hip dysplasia in dogs (through December 2016). The data are reported as number (or %) of dogs with excellent hips and number (or %) of dogs judged to be dysplastic. These data are divided into dogs born in 2011-2015 (so all dogs evaluated are at least 1 year old), and the same statistics for all dogs in the database (including dogs born 2011-2015).
| I have downloaded these data and graphed them various ways to make the information more accessible. Because there is a large number of breeds, breed names are almost impossible to read on the whole graphs, but you can download a copy of the file or I have split the graph in two to improve legibility. The data are presented both alphabetically (so you can find the breed you're looking for) and by rank (so you can compare with other breeds). The files for the large graphs can be downloaded. There are a few notable points (for dogs born 2011-2015):

Total & Recent DysplasticIndicated for each breed are the % Dysplastic reported in December 2016 for dogs born 2011-2015 (green bar) and the Total % Dysplastic over all years (red bar). If a breed has recent improvement, the green bar will be shorter than the red bar. Only breeds with % Dysplastic < 10% are graphed.

Same data as above plotted as % Total Dysplasic - % Recent Dysplastic. Bars above the zero line are for breeds that have reduced the incidence of dysplasia; bars below the line are breeds for which recent % Dysplastic is greater (i.e., worse) than the average over all years.

| We'll cover anatomy, biomechanics, nutrition, and the latest research, as well as how you can reduce risk by understanding heritability and estimated breeding values. The course is online, available anywhere in the world. Materials are available 24/7 Online course Starts 6 February 2017! For info and registration, go to - http://bit.ly/2iEEh1e |
