I put peanut butter in my dogs kong toys, freeze them and wa la! they got something to keep them buzy while I walk out the door for work.
so apparently the above sweetener is toxic to dogs via liver damage.... and it's found in peanut butter, sugar free gum, mints, mouthwash, toothpaste etc.... (check the back for ingredients on stuff if you give your pets a lot of people type foods).
Wonder if it would be in some yogurts.....
