at the university we learned:

dog bites man is no piece of information. man bites dog is a piece of information.

if someone studies newsletters of the past month he could belive that journalists never heared about this principle. or is it more important to inform a journalist than a doctor after the bite of a dog? anyway. what we miss above is: dog owner bites vet clinic owner. it happened in florida and that definitely is a piece of news!
