The best tool for breeders in the fight against canine hip dysplasia (CHD), to come along in years, is the SV's HD Zuchtwert, or Breed value assessment number (HD ZW). The HD ZW number is an estimation of the probability that a dog will produce progeny with CHD.
Historically, dog shows and other related events were developed with a very specific purpose in mind – to select and recognize those dogs with the best breeding characteristics, in order to guarantee the future health, stability and vitality of individual breeds. The practice of dog breeding is dedicated to this purpose, and dog breeders have a responsibility to do what is best for the breeds with which they choose to work.
A well trained SAR dog is a sight to behold. The dog can evenly maneuver the most difficult of terrain with the grace of a mountain goat all the while looking for a trapped or hidden human being. This type of work is often done on the fly, at the drop of the hat, with little advanced warning. It requires a talented dog and a special handler willing to invest the time and effort.
