Sandra has three dogs: a husky, a golden retriever, and a chihuahua. She wonders what types of food dogs like the most. She feeds the husky and golden retriever a bowl of fish flavored dog food in the morning. Then she takes them on a long walk and feeds them chicken flavored dog food for lunch. Then they rest at home for the afternoon, and she feeds them beef flavored dog food for dinner. She feeds the chihuahua a cheeseburger for every meal.
