Hello how may I help you? I'm curious about how much food my dog should be eating in a week? What kind of dog do you have? It is a mutt What is its weight? Between 50 and 60 lb Would you say that is a healthy weight? Yes he is not obese A 50 - 60 lb dog should eat around 5 - 8 lbs of food per week. I go to a 25 lb bag every two weeks Though a Maybe 2 and 1/2 If you believe your dog is at a healthy weight then there's nothing to worry about, feeding can vary greatly from dog to dog, just like people.
