I don't see how you could judge him without ever showing Dogues, by simply looking at a VERY general on-line breed standard. Any purebred dog SHOULD fall within the standard... my little rescue BC falls into his standard, and he's FAR from being breedable. He's adorable but sadly he could not win any shows, ever.

The fact is that not just dogs who fit into their standard should be bred, the absolute BEST dogs who are PICTURE PERFECT examples of their breed should be bred, and only those dogs. That is the whole reason there ARE shows. If the only guidelines for breeding were "must conform to standard somewhat." then why even show dogs?? The entire reason for conformation showing is to prove breedability and soundness of the dog... your dog might look like a great example to you, but to a judge that's been judging Dogue's for decades he might be way off of breedable. That is why, even in a gorgeous purebred litter like Kara's, there are mostly "pet quality" puppies and usually at most one or two "show/breeding quality" puppies. Just being a purebred does NOT make him worthy of passing on his genes, as adorable as he is. Please do look into showing, don't just judge him on your own, and consider only studding him out to tested, show quality, sound females with experienced owners.
