• [quote=gsicard]The question of temperament testing puppies have always given me pause for thought. I have see a recent documentary on National Geographic Channel where a Caucasian Ovcharka (Mountain Dog) breeder demonstrated the method of temperament testing a very young puppy as a way of determining the "level of aggression" of the puppy. The method is commonly used by breeders and is called the "muzzle shake". It involves shaking the puppies muzzle and judging their response to that stimuli. Scientific research has failed to find that puppy tests can predict adult behavior. So why would breeders continue to advocate such practice when many of the premises upon which the puppy tests are based are invalid and unproven? So I guess the bottom line, in my opinion, is that puppy temperament test do not predict adult bahaviour. A puppy buyer would be better served by asking the breeder for their prediction on the puppies behavior and forgoing the temperament test as a method of prediction. Your thoughts on this subject will be greatly appreciated.[/quote] The pups on National Geo show were fearful of being on their backs and having their muzzles shaken. Regarding puppy temperament tests, I've read the same report of the current research Gary. Dog World magazine published a good overview article a few years ago. Haven't seen much discussion of it online though.
