Kevin here on ETHD is the most realistic person I have been around involving the dogo. He's not afraid to cull one or several when needed, and has been around them as long as anyone else I know in the states.
Even though he may be a Dogo enthusiast, he remains objective of the breed, and has been around enough Dogos from different kennels, that I would take what he says to the bank.
Add to that, when I bought a Dogo from him, he gave me a price. Then sent the pup to me and said not to pay him until the dog was ~18 months old... How many Dogo breeders do you know that are more interested in the advancement of the breed than the money they get from a litter?
