How can a police dog be called a bit of equipment?

Is it not a life? Wasn't it helping to save a police officer from being knifed or bottled? Wasn't the boy he bit told to stop?

The sad individual who gave the order to put this dog down should be put but down himself.

Aren't human beings animals themselves? So what right has he to play God?
