The "dog food tastes better in someone else's bowl" phenomenon

This phenomenon just cracks me up! Stella and Sophie run into the puppies' pen when I open it up to gobble up their food... The exact same food that is in their bowl in the next room. The puppies eat more heartily in their Mama's bowl too! Two years ago I had to switch dog foods to one that all three of my dogs could eat which is tiny kibble because of the poodle. I would put her food in a tiny pink porcelain bowl and Stella's food in her large purple porcelain bowl, and they both went straight for each other's bowls even though Sophie's bowl only held a cup of food! Stella would eat it and look at me like "refill please". Even when I switched to one food, they still did that! I eventually went to one bowl of food. Haha.
