The standard is as follows:
"Muzzle - Very broad and deep, width is almost equal to its length, which reaches approximately one third of the total length of the head; the depth of muzzle is more than 50 percent of the length of the muzzle. The top and bottom muzzle planes are parallel, and the nose and chin form a perpendicular line. Viewed from the front, the anterior face should look flat and form a trapezoid, wider at the bottom. Muzzle is not overly narrow or snipey."
I don't mean this to be offensive, just factual, since you're asking. As far as a show standard, yes, he's very out of standard (from the photos I can see, his muzzle is about half of the length of his head instead of the third it's supposed to be). I would also not think he was pureblooded CC if I saw him on the street. His size (he's heavier than my quite large Great Dane puppy) and head are very incorrect and make me wonder what his breeder is trying to do with their lines. They're clearly not breeding with conformation in mind, so what are they trying to accomplish? Do they work and/or title their dogs?
I'm not a "standard purist" and think a lot of changes need to be made to the world of dog showing, but I do think that bigger does not equal better, and anyone breeding CCs that are heavier than Great Danes of the same age needs to take a step back and examine exactly what they are trying to accomplish with their breeding program (besides making profit).
That all being said, there's no good reason on this earth to be rude to someone and insist their dog isn't purebred when they inform you that it is. It sounds like this guy was just a jerk. The fact that Drago doesn't look like a standard CC doesn't mean he isn't a great dog, or that he won't be a great companion or live a healthy, long life. I'd suggest you ignore this person and continue on enjoying your dog
