Ok how is this...my girl got her PDC yesterday (1st try) after only being shown the bicep and suit for a couple months.
It is not the title that makes her breed worthy it was how easy it was to transition her from IPO (bitebar/forarm sleeve) to PSA (bicep on a suit) that makes her breed worthy IMO.
Or when I introduced my then IPO only dog to a civil bite, she took it without hesitation...
(this was her second session on the hidden sleeve, didn't get the first on video)
Any shmo can train a dog for a title...and flaws can go undiscovered when you don't work a dog. She has her strengths and weaknesses, every dog does...they are not machines. I asked someone about a stud and she said he is perfect (bull****)...she also bought him titled and has rarely worked him. One must become a student of the working dog to know what is truly before you. JMHO
