I have owned three dogs in my adult life, all of them excellent dogs, mixed breeds, recues from kennels and such. One thing they all had in common is a set of ears that are like sonar and finely tuned to sound that the little roller on small cheese slicer have when it rattles on the handle. There could be an F-18 or F-15 flying over my house in full afterburner, and if I'm getting the cheese slicer out of the kitchen drawer and they are at the opposite end of the house, they can still hear it and before you can blink an eye, they are their sitting at your feet whining and looking for their piece!! No matter how careful I am to be quiet about it, they hear it. Never mind recommending wrapped individual slices, they have that sound of the wrapper coming off in their sonar range also!! This has to be a common thing among dogs, ya think?
