Do you support police officers who shoot dogs that is charging or having an intent to harm the officer's life?

Of course. Would you prefer the officer to get chewed up?

Yes
100%

I got bit if I had a gun I would have shot the mutt. The dog was not of value to the owner and some how was not trained so bang, check mate.

Were I live. Never heard of a officer shooting a dog. They take them out with there club or rattan. Sometimes with a hammer if they know a bad dog is in the area. So if you had police. This question would not need be ask.

Yes. Dogs have a purpose in this world.

No way, but I do support them getting the sack from their jobs.

Yes, of course. Especially if the dog is a BIG one and there is no other alternative.
However......each case should be judged on its merits.

No they got other weapons to use
