Lorraine I personally don't know what vets are allowed by their license to do in Paris, France; how-ever I do know here in America many general vets do fix Luxating Patella, and are skilled enough to ddx'd the LP and for some even give a credible grade to it. For me no general vet would ever put a knife to my dog for LP or Leggs Perthes ie Femoral Head Surgery.

The issue of cross breds and "multi breeds" ie the old acronymn of mutts and their health will continue to be an "issue", as as you well know no health databases are extant that report on these concerns. We all have our biases, based on the little of the dog world we do interact with. Until we get scientific data on a large enough cross section of the population done in a meaningful way, there is only your opinion, my opinion and the neighbour's next door's opinion. I personally see many mutts (IMO) that have either hip or elbow dysplasia (likely so), doing their doggy best to get by, as they are walked by their owners. In fact because my interest is in movement, I am always observing gait when out and about. I an cognizant how-ever that my many years of observing dogs, purebred, mixed what-ever, and no matter how many dogs I have observed; is in no way scientific knowledge. I do not subscribe to the view cross breeds are healthier, or unheathier then mixes. I simply Do Not Know the answer, as there is no bulk of scientific evidence to support my opinion.
