A Bad Day For Ribbon

Ribbon is getting big, and as she grows, she is getting curious about life. What's over in the neighbor's yard? What's that big, loud thing driving past the house? That squirrel should be chased, shouldn't it?
Robby and Amber are doing the best they can to keep Ribbon safe, but one day, Ribbon runs after a cat and gets hit by a car. She is hurt badly, and has a long road to recovery ahead of her. Its only at a time like this that Robby and Amber learn how many friends Ribbon has already made, and how many people care about them.
Can Robby and Amber keep up their spirits and help Ribbon get better, or will the accident cripple her for good?
