* Summertime: Dog days are a colloquial term for the hottest days of summer, typically July and August. The book takes place during Greg's summer break from school.
* Lazy Days: Dog days are often associated with laziness and boredom, much like the feeling of summer vacation for some kids. Greg struggles with this, trying to find ways to entertain himself and avoid being bored.
* Hot and Sweaty: The title reflects the hot and humid weather that Greg experiences during his summer adventures, including a trip to a water park and an attempt to get a job at a local ice cream shop.
Overall, the title "Dog Days" accurately reflects the themes of summer boredom, heat, and Greg's attempts to find fun and excitement during his vacation.
