Dogsitting

Looking after this dog for a couple of weeks, he seems nice enough. The problem is I have no idea how much food and water to give him, How the hell am I supposed to know about a dog's eating habits. As breakfast time came around, I just had to wing it. "A couple scoops will do you" I apprehensively said. As I served him his meal, he turned to me and gave me a sickening look, Almost like I'd killed his family member or something. I think I'd given him too little.
