great article, thanks for posting it.
Pits and Rotts, together with their recognizable mixes, make up about 7% of the U.S. dog population, but account for 70% of the fatalities and 83% of the disfigurements.
i guess that answers my questions.
i dont think i could carry a fire extinguisher with my on walks with my yorkie, but i will start carrying my bear spray. If the problem the article states with pepper spray is the small size, then the larger can of bear spray might be effective enough.
