First off, I have a dog and treat him very well. There's a verse every dog owner should have memorized Proverbs 12:10 A righteous man regardeth the life of his beast: but the tender mercies of the wicked are cruel. However, don't be fooled by the "loyalty" bit. A dog will be loyal to the hand that feeds him and primarily for this reason. I have confirmed this with dog keepers and trainers. If you have any doubt don't feed your dog and see what happens. Given enough time and circumstances your dog will eat you.
