Sorry for the loss. I believe the Breed of the dog shouldn't be an issue here. It's policy, tactics and common sense at play here. I often ponder what would happen if something like this or a mistaked "no knock warrant" was ever served at my house. My german shephards would altert/ the cops would shoot, me hearing intruders shootng my animals in my home would appear guns blazing. It would be hard to see where the misunderstanding would stop at that point, but there would be no good outcome. This isn't the middle east an officer shouldn't enter a home without announcing. The SOP needs to change IMHO. If policy wasn't violated based on what's been said it sure seems common sense was.
