Here's Andy's pedigree:
http://pawvillage.com/pedigree/pedigree.asp?ID=QNDRRLV0OC
I wanted him based on the looks of his father Devil'n. He was a lot tighter and typier then what you normaly see around here.
Not everything is Sch in his pedigree, but before the sire and dam, there are a lot of good high drive obedience dogs.

This is Tony:
Multi V-1, Multi BISS, A/C CH Von Boylan Antonio Banderas SchHIII, BST, AD, BH, TT, CGC,

The multi V-1 is from German style shows. He rated a V and won his class.
Multi Biss is AKC. He won Best in Specialty show (Rotts only)
Many times and the A/C is American, Canadian conformation Champion.
Then its his Schutzhund 3, Breed suitability test, BH for schutzhund, Temperament test from the american temp. test society, and canine good citizen from akc.

I just picked him because he had a fair amount of letters in front and in back.

To know just how much those titles mean on that dog, you have to either know people with first hand knowledge, or put your trust in the breeder of your dog, that they know what those titles bring to the pedigree with that dog. That is what I think you are paying for with a pure bred dog.
