My previous beagle Molly got into a 5lb. bag of cat food once and ate the entire bag. She also was very lethargic and bloated, and had diarrhea for two days. I took her to the vet to be checked, but he no treatment was necessary. I'm sure Bailey will be alright, but keep an eye on him for the next couple of days. I wonder what Ruby was doing while Baily was chowing down???
