I don't condone killing dogs, in fact I loved my dog like family when I had her. If this happened to my dog, I would be extremely angry with the guy. However, I do condone defending yourself from a dog if you feel threatened. If the guy felt threatened, he has a right to defend himself. No matter how ridiculous that sounds to any one of us because it was a pug.
It's clear that this lady
loves her pugs. They're adorable, and it's absolutely awful that this happened. Yet, she has to be more responsible as a dog owner. I would never let my dog off a leash when I wasn't in a dog park. It's just common sense. I want to protect my dogs from strangers like this, just as much as I want to keep her out of harms way from herself (running into traffic etc.)
