seems to be happening more and more frequently these days almost like there's a policy to terrorize people by shooting their dogs. strays. off leash. officer running through your backyard in pursuit of someone else. officer coming to your house by mistake. officer coming to your house on purpose. whatever. it's a disturbing shoot-first-ask-questions-later trend and frankly I don't buy the boilerplate "the dog was aggressive and baring its teeth" that all these jackboots put in their official reports (which seem to be at odds with witness statements in every story that comes across my news feed).
I've encountered dozens of strays/off-leash dogs the last few years and never once felt threatened by any of them - in most cases I've been able to get them and notify their owners or walk them home. I have no professional training in law enforcement or dog-handling.
