Hi~
My two cents...

Sliced hot dogs, dime thin , quartered, sprinkled with garlic salt/powder, nuked until crisp(not greasy), and the smallness of the treat, always has the dog wanting more, and therefore, "attentive". The garlic has a strong aroma, so they are looking for it!

Noises? An air duster. Usually have one in my camera bag anyway, so, one day, just a quick burst, worked in a pinch, and most photogs carry them?
