Well, that list is ridiculous. When I worked at the shelter, the tiny dogs were way more unstable and nippy than the big dogs. It was more of the lab/shepherd mixes that were bity. I got bit once, not terribly and didn't even bleed, by a white German Shepherd, in the whole 8 months I worked there. But, I was also very cautious and aware of each dog. I left aggressive dogs alone. I have a thought about the list. It seems that most of the dogs on this list are either "spitz types," "bully types," or large/giant breeds. Even Boston Terrier and Pug are smooshed face "bully" dogs. Looks like a list made out of prejudice, not research, to me. Dalmatians aren't even on that list...
