Someone (can’t remember who?) was talking about their dogs losing interest in the food before they finished the bag. Depending how long it takes to get through the bag, this could be one cause as to why they lose interest. I just read this in the Feb issue of Whole Dog Journal:

“….The longer the food is exposed to oxygen once the bag is open, the faster it oxidizes. While buying very large bags makes the most economic sense….., it may not always make the most sense for your dog’s health. Many dogs start turning up their noses at a food by the time you reach the bottom of the bag, because by that time, the fats in the food may be quite rancid – and dogs’ noses are far more sensitive to the odor of rancid fats than our noses are. Veterinarians have a phrase for what happens when dogs are not fussy and eat rancid food, suffering digestive upset after meals: ‘bottom of the bag syndrome.'”
