I used to look at dogs and think that if any other sentient species came by, the things we'd done to an apex predator would be sufficient to mark our species for quarantine at best, but I was playing with a friend's dog the other day and it occurred to me that we've aggressively selected for the happiest, most loyal, friendliest critters we can find - that's what we want, that's what we want to be around*. The world's complicated and our actions in it don't always reflect us at our best, but there's something redemptive about our choice in companions.
(*Yes, some dogs are bred to be dicks, and some people are dicks, but most dogs are good dogs, and most people are, too.)
