Sure it does when you look at how cows are slaughtered to make those tasty burgers you eat. They get shot in the side of their heads with gas powered hammer which doesn't always kill them. Then they get their throats slit and bled to death.
No different than throwing a dog over a cliff.
So u condone and can justify this action
. So you would have no problem if i decided to kill ur dog as, according to you, "cows are slaughtered all the time". So because animals that are specially breed to be eaten are humanely slaughtered, that makes it ok to kill other animals?
Oh and last time i checked, most people dont eat dogs, so your point makes no sense whatsoever.
