I dont trust any dog unsupervised with my daughter.
Ever.
I like my dogs as much as the next guy, but would you let your toddler wonder off into a cow pasture where a rogue bovine could reach her faster than you? Would you let her go play in a horse stall where even with a well mannered horse, 1 accident could end her life? Why, if you know what your pit or even cur can do to a hog with way thicker skin, would you wanna be all macho and let the dog be unsupervised around the most beloved person in your life. If your kids are older and know dogs, its different but as for my duaghter, it ain't happening till I know the question changes from trust a dog around the kid to trust the kid around the dog.
