PK, as far as just shooting the dog goes, I agree with you.
As far as firing the gun inside city limits goes, there are prosecutors who will want justification for deadly force, or they will press charges - since deadly force will have been used in a populated area.
(Edit: Legally, this is about potential bystanders and human victims, not the dog; I had a friend charged with discharge of a firearm within city limits for shooting a rattlesnake in his backyard.)
Depending on where you are, and where any stray bullets go, there can be felony level charges.
