40 free Diary of a Wimpy Kid: Dog Days trivia questions with answers — literature quiz, new questions added Oct 2026.
Dog Days is the fourth Diary of a Wimpy Kid book, and the one that follows Greg Heffley through a whole summer vacation. He wants to spend it in front of a screen with the curtains closed. His mom wants family togetherness, and almost every plan either of them makes goes wrong. This quiz covers the book from its opening pages to the final entry: the country club, the town pool, a doomed summer job, a birthday that disappoints, the arrival of the family dog, a beach trip with the Jeffersons and a video game contest. A few questions look at the cover, the book's place in the series and the 2012 film adaptation. It is written for readers who have just finished the book, and for teachers and parents who want a quick comprehension check. Every answer comes with a short explanation, so it works as a classroom review, a book club warm-up or a printable book quiz.

Q 02What stalks the victims in the horror movie Greg and Rowley watch at a sleepover in Dog Days?

Q 03Which country club drinks land Greg and Rowley with an $83 tab from Mr. Jefferson in Dog Days?
Smoothies
Smoothies were the culprit: the boys kept writing Mr. Jefferson's account number on the tab, unaware anyone would have to pay. Greg's mom later takes his birthday money to settle it.
Q 04What is the two-button cell phone Greg Heffley gets for his birthday in the book Dog Days called?
Ladybug
Ladybug is the phone's name, and it can only call home or the emergency services. Greg had hoped for something far better and writes it off as junk.
Q 05Which boardwalk ride does Greg long to go on all summer in Dog Days, only to feel sick on it?
Cranium Shaker

Q 07Where do the Heffleys forget Greg's mom on the drive home from the water park in Dog Days?

Q 08What summer business do Greg and Rowley start to repay Mr. Jefferson's country club tab in Dog Days?
Lawn mowing
Lawn mowing is the plan, sold under the V.I.P. name, though neither boy has ever used a mower. Their only customer refuses to pay because Greg steered wide circles around every dog mess in her yard.
Q 09Which fish does Greg Heffley buy at the mall pet store in Dog Days, only for Rodrick's to eat it?
Angelfish
An angelfish is Greg's pick, while Rodrick chooses a fish labeled aggressive and Manny buys fish food, which he eats. Mom later puts both fish in one bowl, with predictable results.
Q 10Which Game Hut prize does Rowley pick over a place in the national playoffs in Dog Days?
Chocolate-covered raisins
Chocolate-covered raisins, a giant box of them, are what Rowley carries home. He had won 15-0 only because Greg's thumb was too sore to work the controller.
Q 11Which town pool lifeguard does Greg Heffley wait on in the book Dog Days, hoping to win her over?
Heather Hills
Heather Hills is a high school student and the older sister of Holly Hills, and she barely seems to notice Greg. He gives up after a child is sick by her chair and she seems to expect him to clean it up.
Q 12Who takes in the Heffleys' troublesome pet in the book Dog Days and goes on to spoil him rotten?
Gramma
Gramma agrees to take the dog, with Greg's dad supplying a week's worth of food and water. By a later book she has fed him so many table scraps that Greg barely recognizes him.

Killer
Q 21Which video game do Greg and Rowley play head to head in the Game Hut contest in Dog Days?
Twisted Wizard
Twisted Wizard is Greg's favorite game, and earlier in the summer he even prays to get past its third level without using his bonus health packs. He loses the contest to Rowley anyway, without scoring.
Q 22What animal does Rowley dream is hiding under him when he wakes Greg on the beach trip in Dog Days?
A chicken
A chicken hiding beneath him is Rowley's nightmare, and it jolts Greg awake in the bed the two boys are made to share. The rental also turns out to be five miles from the sea.
Q 23What do Greg and Rowley poke up through a gap in the boardwalk to trick passers-by in Dog Days?
A dollar bill
Killer gets to the cake first, so Greg's mom simply cuts away the parts the dog did not touch. Greg loses his appetite when the dog throws up birthday candles under the table.
Q 14What does Rodrick convince Greg their dad is secretly planning to do with him in the book Dog Days?
Sell him
Sell him is exactly what Rodrick claims, pointing to a note he has faked in their dad's planner. Greg panics and calls the police; the real plan was a father-son outing.
Q 15Which classic novel does Greg's mom assign him in the summer book club she runs in Dog Days?
Charlotte's Web
Charlotte's Web is the pick, and Greg guesses that either the girl or the pig will not survive to the final page. He is made to sit at the kitchen table until three chapters are done.
Q 16What does Rowley use to whack Greg while the two camp outside the Game Hut overnight in Dog Days?
A mallet
A mallet comes down on Greg after he reaches through the tent flap to give Rowley a fright. The injury costs him the video game contest that follows.
Q 17What does Greg Heffley call himself at the start of Dog Days to justify a summer of video games?
An indoor person
An indoor person is how Greg sees himself, happiest with the shades drawn and a controller in reach. His mom has other ideas and keeps pushing him outdoors for family time.

Li'l Cutie is due to end in August when its creator retires, and the two even consider throwing a party. Their hopes are dashed when the creator's grown son decides to take over.
Q 19What color is the cover of Dog Days, the fourth book in Jeff Kinney's Diary of a Wimpy Kid series?
Yellow
Yellow fits a story that never leaves summer vacation: the diary runs from June to August and ends before school starts again.
Q 20What does Greg snap against Rowley's arm on the beach trip in the book Dog Days, getting sent home?
A rubber band
A rubber band leaves a red mark that makes Rowley scream and tell his parents Greg burned him. Greg's dad then has to make a four-hour round trip to collect him.
A dollar bill is the bait in a trick Greg learned from Rodrick: yank it away just as someone bends down. It ends when one quick kid grabs the money and refuses to give it back.
Q 24What name does Greg's mom give the book club she starts for neighborhood boys in Dog Days?
Reading Is Fun

Q 25What ends the Heffleys' half-price day at Slipslide Water Park soon after they arrive in Dog Days?
Rain
Rain starts just after the family has put on sunscreen, and that is the end of the outing. Greg had already talked his mom into renting a double stroller so that he would not have to walk.
Q 26What does Greg's dad give the police officers who answer Greg's emergency call in the book Dog Days?
Baseball tickets
Baseball tickets were meant for a father-son day out that Greg's mom had arranged. After a long talk with the officers, his dad no longer felt like going.
Q 27Why does Rowley's family stop inviting Greg Heffley to their country club early in Dog Days?
He kept complaining

Q 28What has fallen on the ground at Greg Heffley's feet on the front cover of the book Dog Days?
His ice cream
His ice cream has melted onto the ground, leaving Greg with an empty cone and his trademark frown. He is dressed for the pool in swim shorts and sandals, a towel over one shoulder.
Q 29Which part of the town pool does Greg Heffley dread having to walk through in Dog Days?
The shower area
The shower area has to be crossed to reach the water, which is why Greg resists going with his mom and little brother. He goes back willingly only once a crush is working there.
Q 30Which fruit at the Fourth of July picnic in Dog Days does Greg fear because of a tale from Rodrick?
Watermelon
Watermelon is handed out free at the picnic, but Rodrick once told Greg that a swallowed seed would grow into a whole fruit in his stomach. The fear has stuck with him ever since.
