Of all the people and all the places in the world, you come to VGChartz for advice on this situation?

I'm gonna be honest with you here.

Too many people in my neighborhood don't know what the heck they're doing with their dogs. They don't know how to properly train them to be obedient, walk the sidewalk properly, and approach other people/animals. I have a dumb lady on my street who literally allows a chihuahua to call the shots on which direction she walks the darn thing. I've seen her go past my house walking the dog and then whip around and go the other way because the dog decided to turn that way. Then she goes up into the lawn because that's where the dog wants to go. Another neighbor's larger dog gets out once and a while and they have the toughest time trying to catch him because the animal won't listen when they say "Come boy".

I've also seen a small few who have properly trained their dogs. Who can be in the front yard and not chase after cars, people, or squirrels running by and their isn't a fence to stop them. Who obey voice commands without hesitation.

My point is, you haven't trained your dog properly. Your idea of training is to set up a fence or put a leash on him. But a properly trained dog doesn't need those things to demonstrate obedience.

And so now you have a dead cat as a result. And honestly, if the scene of the killing was gruesome, I'd be worried to keep that dog as a pet. You never know what might cause them to snap.

It's a tough situation, sorry but personally if somebody's dog killed one of my cats I wouldn't rest until that dog was dead, it's not 'just' a cat it's someone pet, companion or even part of the family.

Frankly, you should face prison time for this, and your dog should be given to an owner who will treat it right.

I don't see how your dog can get put down. Your analogy about cats and small animals is exactly why. I'd say financial fine or payment is more than enough. Btw, you should also get a lock on your gate. That is irresponsible.

This thread blew up considerably.

OP, you won't get any useful information out of anyone here. You'll either hear cat-haters say there's nothing wrong with the situation or you'll hear cat-neutrals and -lovers say the dog should be put down. Tell us what Animal Control tells you.

Really so a dog mauling a cat and a dog mauling a 5 year old girl is the same thing?

Bruh. 

Come back when you're a cat and say that.

No, I mean the attitude that a dog shouldn't be put down for killing a cat, but it should for a dog is ridiculous. I  obviously didn't mean humans, stop nitpicking. Either way, it's arguable that they should be put down whether it's a cat, dog, or a human. I think hurting a human would be the worst, because I'm a human and am biased towards them, but the point is that letting your bias get so out of hand to the point where you practically don't care about the death of an animal at all because it isn't part of the "dog master race" like OP here is too far. 

@ bolded: The OP already said he sees cats as lesser beings than dogs and admitted that he's biased which is why he doesn't think his dog should be put down for it, so this makes no sense.
