@agilebasenji:
Re +punishment - okay, I never touched a hot stove again, but I know of several dogs who repeat the skunk/porcupine encounters. So, while I won't debate +P works, it's very hard to get it right.
I'm laughing because one of my friends had a dog that routinely went after porcupines every chance he got! She figures she put the Vet's kids through University because of that dog. The problem was, he invariably killed the porcupine, so I guess the positive result was worth it for him. I concur, difficult to get it right. That's the nice thing about the electric fence. It doesn't make timing mistakes.
I found something else of interest, with the help of Google. It pulls information from a number of studies. Definitely worth the read, especially for breeders, I would think…..

I wonder why Basenjis so often get used in research? Because they are different…..and an ancient breed? Quote from above link, emphasis mine:
_At 12 weeks a puppy is easily frightened. Confinement and hand feeding enable it to accept contact with its laboratory handler(s) but not with strangers, and it still prefers the presence of dogs to that of humans (Scott and Fuller, 1965).
This fearful reaction has been found in all breeds tested. When put on the defensive a ****er's bite is "softer" than that of other breeds tested (basenji, terrier, beagle, sheltie).
According to Fuller (1961), puppies raised in isolation in a laboratory develop adequate socialization to humans if they receive two 20-minute periods of human contact per week. This short contact, however, is not enough for basenji puppies; this variability is thus truly linked to breed (genetics) (Scott and Fuller, 1965)._
