Meaning that a pit bull (already known to be a troublesome breed) that requires such a collar is likely a monster dog.
I use that collar with my GSD when we go walking to keep her from walking me. I use that collar with neighbors' dogs I dog-sit because they need it (lack of discipline, won't listen otherwise). Pit bulls likely need that collar to keep them from chewing on peoples' necks, or biting the ears off of babies in this case.
See you in the next "pit bull attack" thread!
LOL!
