Probably the best thing to happen to you
I also had a dog that managed to get to a litter of kittens in the closet...
I came home to "kitty parts" all over the master bedroom... even had a "back half" on my pillow
she was another shep mix. Friendly as all get out but that instinct is always there and only humans have a chance to control it 100% of the time.
I have a North Carolina buddy who's wife will wreck numerous cars each year running down animals of all size... She will hit a tree just to run down a bunny and she takes down several deer per year with the "Chrome Bullet" as she calls it
Don't even mess with her man!
