my yorkie loves to chomp on ice

I didn't find this out until after I dropped a cube on the kitchen floor and she zipped after it like lightning! At first I was afraid of her having it but then I saw that it was OK. Now whenever I opt not to give her her chicken treats, she thinks she is getting something special when I toss an ice cube on the floor. I especially like to give it to her on a day like today, when she is hot after her walk at the park. It's so cute the way she skids after it and runs off with it in her mouth!
