You called the cops and knew they were coming. Of course, the dog will get excited when a cop car pulls up, lights flashing, strangers getting out. Tie up the poor dog or leave him in the house.
More proof (if any is needed) that today’s cops are NOT your friend.

Another case of failing to understand Standard Operating Procedures:
1. Arrive in APC.
2. Shoot chihuahua.
3. Taser owner.
4. Eat donut.
Cowardly cops acted like cowardly sissies, and covered up their punkish, small penis inferiority by issuing a summons, transferring all the blame onto the victim. Sure the victim should have had her dog secured, but real men would have known the lab was just having a good bark.
My first reaction is to get pxssed because we hear of these so many times. Is it gross arrogance by those whose role is to protect and serve the public, from whom their paycheck originates. Or are there circumstances that we are not aware of that warrant it?
The discharge of a firearm in public and killing of a pet needs to be taken seriously and be retained on an officer’s record forever. I’d favor a citizens panel to investigate and review these types of cases and not rely on an internal investigation.
I usually shoot my dog before I call the police. It saves time.
