My dude, I literally handed you a refutation on a silver platter. Look at the wikipedia link. All you have to do is scroll down, there's a column for breed. Anyone with MS Paint can make a bar graph, it is just not a source. The source on yours, Animals 24-7, looks like an alarmist publication, go to their website and the literal first story is "“We can’t live like this in a world where dogs eat children”. Come the fuck on.

Here's one issue with relying on media reports as a source: dog breeds are highly likely to be misclassified. If a boxer attacks someone and a bystander thinks it was a pitbull, that is going to get reported as a pitbull attack. The CDC stopped collecting dog breed information in bite statistics because it is so difficult to accurately classify.
