A Dog's Life is the name of both a movie, an entirely unrelated one act play, and also an unrelated book. Please list the separate tropes under the appropriate headings.
The book:
- Tear Jerker: Squirrel's life isn't pleasant. She's abandoned by her mother at too-young an age, loses her brother after losing their mother, spends most of her life near-starvation and lonely in the streets, sees her Only Friend Moon get hit by a car, and near exclusively meets neglectful and abusive owners. Eventually she does Earn Their Happy Ending as a senior but it's still a Bittersweet Ending because her owner could die before her, making her future uncertain, and she never did reunite with Bone.
