I am sorry for seeming to not speak to you directly Occy , I try to not bring names into things if it can be helped in such an emotional thread.
I have said many times now that yes,the best of the breed are the goal to breed with.
But this does not gaurantee a non DA litter .
Perhaps that is the part you are having trouble with Occy.
That these breed/breeds are geneticly ( broken record much?) predisposed to DA.It is trait and one needs to be aware of it.
These dogs also can be late to fully mature.
A dog that is non DA for the first few years ,can and often does start to display DA at around 3 years of age.
