I have a Great Dane. I also have a Great Pyrenees and a Border Collie mix. Alright, I can see vitamins and an egg every now and then, but 5 Lbs of dog food and 2 Lbs of hamburger! He must of been extremely over weight! I buy 1-40 pound bag every 2 weeks! And all 3 of my dogs are on the heavy side. I'm curious! But why would you feed him 2 Lbs of hamburger? I apologize if I'm sounding rude. I just can't see that amount of food for 1 dog in a day's time. I'm not an expert but I do work with allot of veterinarians -And I know hamburger isn't good for dogs.
