Cite an example where a person was charged with First Degree Murder (of a police officer) for killing a police dog. Killing a police dog is not the same as killing a police officer. Sure...in an emotional context people may say that...but it's hyperbole and everyone (at least reasonable people) knows that.
Having said that, killing a police dog should carry a hefty punishment. A lot of time, effort and expense goes into acquiring, training and maintaining police dogs. You'd be punished for destroying another piece of high value police equipment (like a vehicle) so it should be no less for killing a police dog. You'd also be charged for killing your neighbor's dog while committing a crime (which is when most people kill police dogs) in most places.
