Earlier quoted context omitted.
I can't argue with an opinion, but this is just mind-blowing to me. Judging by everyone else's comments, it doesn't appear like yours is an isolated opinion either. I'm just at a total loss for words. I had no idea so many people value animal life above human life.
What if they value all animals' (that is, including humans') lives equally? Would you rather save someone close to you or a stranger?
You may value a dogs life as much as a human, some do. But those same people don't go around with extreme care to avoid stepping on an ant, and would kill insects if they where an annoyance or risk to health. So they do stablish a difference between some animals, where ants are in a different tier than dogs, but humans and dogs are together in the same tier.
Personally I don't think it makes any sense. I do value animal lives greatly, and between a dog and a man I might save the dog in a split-second gut decision (and regret it later).
I reckon many people use feelings to guide (or greatly inform) their morality. Which might or might not be that bad to be honest, I don't really have a solid basis for my morality either.
