Just like humans, dogs shiver and chatter their teeth when they are cold. Very small dogs get chilled especially easily. The dog's nervous system and other
systems interact in the temperature cycle. The result is to warm the dog to its normal temperature.
Rearrange the steps of the temperature cycle into the correct order.

Place the action that takes place first (Step 1) at the top and the last action (Step 4) at the bottom.
The brain senses body temperature.
Muscles warm the body by shivering and chattering teeth.
The brain detects that the body is too cold.
The nervous system directs muscles to shiver and teeth to chatter.
