They expect you to cater to their every whim. They are moody. They leave hair everywhere. They drive you nuts and cost an arm and a leg. They are tiny women in fur coats.
Dogs lie around all day, sprawled on the most comfortable piece of furniture in the house.
They can hear a package of food opening half a block away, but they don't hear you when you are in the same room. They growl when they are not happy. When you want to play, they want to play. When you want to be alone, they want to play. They are great at begging.
