gee, we really don't know! http://www.readingeagle.com/article.aspx?id=75318 The Humane Society of Berks County Inc. reported 73 dog bites in the city last year, of which 29 were by pit bulls, or 39.7 percent. . . . . But the state, using incidents reported by doctors and hospitals, claims there were 111 dog bites in the city last year, of which 14 were by pit pulls, or 12.6 percent. A Reading Eagle review of the bite lists showed few duplicates. After removing those, it appears the city had 171 dog bites last year, of which 43, or about 25 percent, were by pit bulls.
