I freakin' hate when people are not responsible for their dogs. My next door neighbor once had a collie, just like Lassie. They let her run around the yard as she pleased without a chain, these people never chained her, nor a invisible electric field that my former sheriff had when he had his K-9. One day I saw her stare the grim reaper in the face, she chased a passing car, and was like AN INCH away from the left rear tire.
3 months later, similar thing happened, and this time she wasnt lucky.
I wanted to tell my neighbors off about the first time, but I felt it would just cause conflict so I just let them ride it out and suffer the consequences.
