I see a lot of conflicting advice online.
I have a 2-year-old, 66 lb. boxer-ridgeback (probably, we're not sure), that, at some point was given an ice cube and loved it. Whenever I make a smoothie, she hears the sound of the freezer door opening and comes running for an ice cube. This is several times a week, but never more than one ice cube each time.
Any compelling evidence that I should stop?
