Love dogs.  Love pit bulls.  I would never have such a powerful breed around my children unsupervised.  If a child pulls the tail of a cocker spaniel he's gonna get bit.  Maybe a couple stitches in the hand.  Same scenario with a pit bull and your looking at permanent damage, disfigurement and in some cases death.  I know that although it's sensationalized in the news, it's still not very likely to happen.  However, I'll never put my children in harms way even if it's a 0.0000000000000000000000 000000000000000000000000 000000000000000000000000 00000000000000000000001 chance.  That's just me.
