* Marty's decision to protect Shiloh: The core of the story is Marty's growing commitment to protecting Shiloh, the abused beagle. This isn't a single action but a sustained effort involving feeding, caring for, and eventually fighting for the dog's freedom.
* Confronting Judd Travers: Marty's ultimate "solution" involves confronting Judd Travers, Shiloh's abusive owner, though this is done in a way that's far from confrontational and more about proving his care for the dog.
* Legal and ethical considerations: The story highlights the complexities of the situation, showing that there's no easy, black-and-white solution. Marty needs to navigate the legal and ethical gray areas surrounding animal ownership and abuse, learning about the importance of evidence and responsible actions.
* The importance of friendship and support: Marty's solution isn't achieved alone. He receives crucial support from his friend Dara Lynn and, eventually, his parents. This underscores the importance of community and seeking help when facing difficult ethical dilemmas.
In short, the "solution" isn't a single event like a court case or a dramatic confrontation, but rather Marty's personal growth and his successful effort to ensure Shiloh's safety and well-being through a combination of courage, perseverance, and the help of others. It's a nuanced depiction of problem-solving that emphasizes the ethical and emotional complexities involved.
