I wish so much that people would just be more responsible dog owners and most of these cases would never happen. It's awful. Because of these three incidences, I've had to listen to soooo many customers over the last couple of days talk about how "all those vicious breeds" (bully breeds, Rottweilers, Dobermans, GSDs, etc.) should be banned and it's heartbreaking to hear.
And the one case definitely wasn't even the Pit Bull owner's fault IMO. He was walking his dogs outside of a park in his neighbourhood on a leash, when the victimized dogs ran out of the park, failed to listen to their owner (and the owner it sounds like failed to listen to the Pit Bulls' owner), and caused an issue with the leashed dogs. It's unfortunate a dog died, but in that case specifically, the poor man and the dogs that attacked and killed the Pom should not be made out to be the instigators/aggressors. It might have ended badly, but they were not the cause.
As to the other bites/attacks, I haven't heard as much about them in detail, but still. It all boils down to stupid people from the sounds of it.
I am grateful that I live in the city that I do, though. Calgary is never one to jump on the "let's ban this breed" bandwagon, no matter how the voters vote on these types of polls. I hope it stays that way.
I do wish the city would properly fence all of the dog parks it brags about though, because at least that one incident could have been prevented that way.
