I need opinions on Nutro Max weight control. I was in Petco yesterday and was all set to buy Nutro Natural for weight management, but all they had was tuna flavor. I then picked up Blue for weight mgmt. There was a Nutro rep in the store and he convinced me to try the Nutro Max. I talked to him about the corn gluten in it and he said its a protein choice. Unfortunately I let him talk me into it. I had originally decided on Nutrol Nat. cuz it didn't have any gluten. My fatty is 18# and prefers dry food. I need to get her down to a reasonable weight. She free feeds and does not exercise. Too fat. My other baby is 8# and is very active. My vet said Juno (fatty) is a little overweight. She's got that wrong, a lot overweight. Back to the Nutro Max. I get it home and am reading the back for feeding instructions, and see the expiration date was 5/09. Imaging, a Nutro rep selling outdated food. This is going back to the store tonight and I'm going to try Petsmart for the Nutro Nat. Weight Mgmt. I am interested to know if any of you use the Nutro Max. It was priced right and on sale.
