A 9 month old 75-80 lbs. Rottweiler, male that will be right at around 100 lbs when he is full grown, how much should I feed him of Blue dog food?

According to the Blue Large breed puppy bag you should feed 4 metric cups a day. So, two in the morning and two in the evening. You should NEVER leave food laying out for a dog or you feed WAY more than the dog actually needs.

Just bought a new bag and read it for ya!

i feed my dogs the same thing, it tells you on the bag and i think it goes by the weight of when they are full grown what they are suppose to weigh. i have a 65 lb english bulldog and 2 bassets hounds and i feed then approx 4 cups per day each, i use blue buffalo basic its easier on digestive system, my bully needs it they are known for sensitive digestive systems and my female basset has food allergies, so i am not sure if all types of that brand are the same, that is why i said to look on the bag i believe it is on a chart on the side and not the back. good luck with your rottie i had one for 13 yrs and loved him to pieces, miss my big guy he was 150 lbs. now i have 3 dogs..lol got 2 pups 3 mnths apart when i finally got over loosing my chaos (rottie's name). rottie is great dog mine used to be able to sense my seizures and was a big teddy bear not a mean bone in him.

I no longer have dogs, but when I did I kept their bowls filled all the time and they ate when they were hungry.
