I assume you're interested in more than the purely subjective opinions of anonymous aliases -- you want the the reasoning (if any) behind those opinions?
Is there any objective basis for holding one life as more valuable than another? (Subjective valuations are irrelevant and boring, to be honest -- we're all much more interested in why those valuations are held), surely?
Humans of course are also animals. But are they only animals and nothing more? If so, then choosing puppy or person is simply a personal and whimsical preference arising from personal circumstances, and therefore entirely boring to discuss.
On the other hand, one can aver (as Classical philosophy and many religious systems do) that humans - in addition to the features of animals - have a nature that transcends the value of any merely physical creature (such as plants and beasts). I am of this school.
