This process is sometimes unbearable to some dogs and they apply different waiting methods.
Benny surrenders to the inevitable wait by sliding down onto the floor, getting flat and sighing a lot
His house mate Buddy feels about the same and picks a spot nearer to the kitchen and flattens out.
Penny on the other hand is a silent, stand and wait-er. She will move occasionally, look out a window but will always come back to the feeding area to check in and silently stand and wait.
Meanwhile Buddy and Benny are getting flatter and flatter in resignation. It's always a relief when it's time to feed everyone. I can hardly stand the tension.
