really sorry to hear whats happened and all the best as to what happens.
Take it there wont be any cctv anywhere or anything that could have picked up the bitch driving off or any neighbours who saw it?!
As said well done for still getting him our the road despite what he did to u, tis an unfortunate reflex that anydog could have!! All the best for both of u, cant imagine how i'd feel if either of my 2 had the same thing happen
