I'm the opposite. I like and respect dogs as animals and I fully expect anyone who owns one to take care of it. But given the choice, a snake's life is worth more to me than a dog's. Dogs can be feeder food for me, just fine.

Now, I wouldn't buy a pet dog specifically for that purpose, but mostly because of how horrified other people get. I don't feel anything more strongly for a dog than I would for a rat as a feeder.
Of course the dog in this instance couldn't do anything to help or hurt the situation. He's just another animal in the food chain. I feel bad when a pet animal of any kind becomes food, and it's worse that the kids had to see it.
