I just put $$ down on a pup from untitled parents. The only reason I found the litter initially was a Youtube clip of some Bitework. The breeder has titled dogs in the past and also has dogs working in LE. That plus the vids were enough for me to take the dive.
What I dont like are fanciful stories that have no provable basis in reality, show dont just tell.
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.
