With all due respect many have deviated from the original story/situation. Perhaps you should let your neighbors know what to expect. Your not my neighbor and for some of you that's a good thing for both of us.
So to answer the questions. 1. bury it deeper. 2. I didn't see it.
Certainly there are lots of OP's about this situation and as for being flamed here goes.
The Apostle Paul wrote, "Everything is lawful but not everything is expedient." It seems to me the same applies here.
Sure it was lawful to shoot the dog, no question about that, but was it expedient...
