Hello how may I help you? How much dog food am I expected to go through within one week? Well, what kind of a dog do you have? That makes a difference. I have a German Shepard A dog of that type should eat at least 20 pounds of dog food a week. 20 Lbs sounds just right. What's the best brand? They are all pretty decent. It's only marketing that justifies higher prices for premium brands. Oh, ok. Thanks for the tip. You are welcome. Anything else you need? One more thing, should my dog eat broccoli? No, that is not advisable. Ok, thanks. That's all I need.
