Canczech must be an exception regarding breeders in Western Canada. The owner has been breeding and working dogs for over 30 years. He is originally from the now Czech Republic and has contacts in Europe and travels to Europe at times looking at dogs. My dog's sire Xly, was sired by Corado z Vetrovej luky who was imported from Slovakia as a pup and turned into such a good producer, the Slovak National Police requested the owner of Canczech, send him back to Slovakia for multiple breedings and he has produced many dogs working for the Slovak National Police. The owner, Tony Nikl does one of the best jobs of exposing new pups to environmental stressors that I have seen. They are exposed to gunfire at a very early age and then increasingly louder gunfire as they mature. They are taught to eat off of a running ATV, and he even puts young pups in a small vest and sends them down a short zip line. While his dogs can be aggressive, they tend to have good discernment and are not sharp and reactive. Depending on the pup you get from a litter, some will need an experienced handler. As a pup, my mine was totally reckless and was not stop biting and there was no correcting or redirecting him out of it. He has matured into calm dog in the house and will come into drive in an instant, but is well controlled due to his training.
