Opinons on my dog's pedigree - Page 1

Hi,

 I got my puppy couple of months ago and I wanted a dog that can do personal protection.  I just wanted to ask everyone what are their thought's on his pedigree and even if they know the dogs in the pedigree.

I love such questions and would like to see some answers which can only come from people with knowledge on dogs, lines and history. I can only comment that Troll is available in so many working dogs pedigrees as I have been looking at many pups pedigrees lately.
