Dude -- my dog eats M&M's like theyre going out style, and it doesnt affect him in any way. My mom's 5 pound yorkie got into her fudge and ate a whole tray -- probably two pounds of it. My dog has stolen a whole box of donuts and eaten every one (twice!). The only health danger involved was me seriously considering shooting him for stealing my donuts!! (Settle down, PETA guys -- I'm a rational person. I sat down with him and had a serious discussion pointing out how dissapointed I was in his behavior, and I set up a 12 point plan of intervention).
Whew -- too much excitement for me -- I'm taking my dog to Taco Bell!
