When I was talking to insurance companies the question about training "vicious breeds" came up... some interesting information... over the last year and a bit, I have dealt with a few dogs that either have bitten people, or have been "reported" to have bitten, or showed "vicious" behavior etc as follows: pointer mix, springer spaniel, shepherd/husky mix, lab/schipperke mix, miniature pinscher, Shar Pei ... oh ya and there was one pit bull that appently bit his owner... turns out he was real...
