Tracking is a sport where the people take the passenger’s seat. The dog is in the lead and is able to confidently do what comes naturally to it, and we must learn to trust in this ability. For some people, trusting the dog and letting it lead are two of the hardest parts of beginning work in tracking.
The personality of a dog is flexible and indeterminate. Dogs can be exuberant or shy; friendly or hostile; fearful or bold; aggressive or passive or some combination of the above. These differences in personality may to some extent be determined by breed, or individual genetics, but for the most part it is based on how and to what extent each particular dog has been socialized.
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.
