Hello welcome
I think that individual breeders do have their own interpretation of the standard but that is also reflected on the quality of dogs they have in their kennel. The kennel you have got your dog from, for me, is a kennel that has always struggled with correct type. Another kennel may have a strong boxer influence so of course they are going to champion that look.
Correct Cane Corso - what is that, for someone who thinks something is correct someone else will say it is not. If breeders all had a dog like say Bayron in their kennel I am sure that each breeders type would be closer to what is correct. I have found over the years that correct for some breeders is what they have the most of in their kennel, which ultimately will take this breed further and further away from the true reality. Once lines are polluted, destroyed with bad breeding decisions there is no magic marker, no time machine to go get these lines again in their pure form, to breed away from the standard and to breed incorrect dogs, will in the long run, destroy the true spirit of the word and perhaps even the breed Cane Corso Italiano.
