Right I was busy earlier but have you heard the saying a little knowledge is a dangerous thing ? Because your clueless ask the owner of the father of the dog I used how he worked his breeding and his demise ,before you try and second guess my breeding plans ?
I believe the dogs grandfather sire side was a 1/8 so hardly anything direct, but they've all got it in them, this is his grt grandfather dam side very bullish but not with any bull for at least 7 gens
Have a look for European breeders who are working their dogs, there is some very good stuff out there look for a breeder with lots of work and a few dogs and not a lot of dogs and very little work
