I was looking for one because I really did not want to go through puppy stuff. I found it next to impossible to find a decent one. I went and saw / tested 3-4 in my area, all had various issues mainly nerves. I just did not trust a lot of the ones I saw posted on PDB and did not have time to drive down and look at all of them. Im sure there are some out there but they arent easy to find.. Unless you want to spend 5-7k at an importer with a decent rep.
Honestly, I didnt even care about training just wanted a good raw product.
Such shy animals are in all circumstances an encumbrance to their owner, who must be ashamed of such a dog, and a disgrace to their race. Under no circumstances whatever must they be used for breeding, however noble and striking they may appear.
