We shouldn't get first priority over animals, they have just as much right to live as we do. Sure thye may not be as intelligent but they can't say "Stop" when they're getting mutated. I'd rather have some mass murderer tested on then some inocent animal. Killing an animal should have the same consequences as killing a human because it's murder all the same. But I don't respect the fact you think Asians eating dogs is disgusting, you probably eat meat which is basically the same, it's only due to the fact we've never heard of eating dogs and we grow to love them as if they were part of the family. They could be shocked and disgusted all the same if they heard some of the things some of us eat.
