Guy comes home to find his guns, iPad, and wife's jewelry have been stolen, so he calls the cops. Deputy shows up, shoots owners barking cattle dog in the head in the driveway, but didn't kill the dog right away. Owner begs deputy to shoot the dog again to put it out of its misery, since his guns were stolen and he can't do it himself. Deputy instead gets back into squad car and drives away, leaving owner to strangle his own suffering dog. More cops show up later with guns and tasers pointed at homeowner, who is now covered in his own dog's blood, thinking he's the suspect until he explains what happens.
Seriously, if dogs scare you that much that you have to shoot one who is barking to alert its owner someone is on their property, maybe you need to be in a different line of work.
