How much comfort can most cows bring you compared to most dogs?
You can't shoot a cow with a gun and kill it. The way they kill cows is by firing two bolts into the side of their head which as far as I know knocks them out so they don't feel what happens to them next.
If you shoot a dog in the head with a gun you'll likely not kill it.
I guess it comes down to respect really. I don't have a problem with the people that eat dogs or any other animal, so long as they don't feel it.
And I don't put humans any higher than other animals, though we don't eat humans, some people do still though that is because that's how they have found to get a source of meat.
Really you can compare all of this to if you had to eat a person. Would you want them to not suffer? If you would then you're a fucked up person in my opinion.
