That's a horrible thing you had to deal with. I support you shooting the dog. Irresponsible pet ownership does not, unfortunately, warrant killing the owner, but he'll now take things more seriously and keep his dangerous dogs on his own land. When I was a kid I raised rabbits as a hobby and a husky came and bit the toes off my dwarf mom right through the mesh floor. I scared the dog off. The next time he came back he killed a rabbit. I caught him, called animal control, and the owners never went and got him back. (They knew I had him.)
Good for you, and pursue legal measures if necessary to get at least the money back to restart!!!!!!!!
