#4 Pit bulls are not good guard dogs, despite their false reputation and despite the fact that many people get them for this purpose.
#5 Pit Bulls are too much love to make good watchdogs.
They would have to be specially trained to be aggressive towards humans (something we are not allowed to do). Even then, their human-loving instincts can prevail.
#6 Razor Edge Pit Bulls and Blue Nose Pit Bulls are two types of pit bulls that are highly desirable.
Razor-edged bulls have a very bulky appearance and an even gentler than usual nature, while the blue nose pit bulls have a very distinct blue/grey coloring. Both types can be very expensive, selling for thousands of dollars. However, this is not an actual separate breed either - both are just variations on the various standard Pit Bull breeds.
