Upon seeing the paw prints on the bucket, and the words "pet safe", one naturally would conclude their dog can safely walk on surfaces treated with this particular ice melter. They're counting on this so their product gets chosen over a competitor's. The "Dogs can safely step on them because they're round!" excuse is weak at best.

With that logic, I can sell "baby safe" chlorine-treated diapers because they use little sticky tabs instead of jagged metallic snaps that naturally would harm baby.
