That also has to do with it. But the major inbreeding that has occurred with dalmatians mostly after 101 Dalmatians has made them rather unsure of themselves. If dalmatians do not get a lot of socialization when young and are not introduced to new things all the time, they become very suspicious and do not know how to deal with situations. This is also partially just how dalmatians are. When the dogs in her basic class were introduced to a walker, everyone was fine with it. Some were more wary than others, but they were all fine. Delta barked... a lot. Lol I had to get a walker and acclimate her to it for a day.

But you are right, owners don't realize this of their dalmatians and so when they do get in a bad situation, they don't know what to do, and may very likely snap.
