To give the dog a treat in Tiny Bookshop, you’ll need a fish—a unique item not sold in standard shops. Standard locations like Mega Marche and Lighthouse won’t have it. The dog’s preferred snack comes exclusively from the fish market.

Steps to Acquire the Dog Treat

• Visit the Waterfront fisherman: Interact with him repeatedly over multiple in-game days.
• Complete his quest: After building rapport, he’ll assign a task to unlock recurring access to the fish market.
• Purchase fish: Once unlocked, buy the treat directly from him at the market.

How to Feed the Dog

After obtaining the fish, simply offer it to the dog. This is the only verified edible item for the dog currently. The fish market restocks regularly, making future purchases hassle-free.
