Builds TheDogs.app's arrival checklist for a breed: what to have before the dog comes home, on day one and in the first week, sized for the breed (crate, harness), with breed-specific items (e.g. ramp for back-problem breeds, cooling mat for flat-faced breeds) and a 'don't buy yet' list. Optional lifestyle answers personalize it (apartment, alone all day, first dog). Use when the user is getting a dog soon, passed a test drive, or asks what to buy/prepare. The list is editorial, not sponsored; it contains no prices or shopping links. In apps that display widgets, a visual card is shown to the user; there, keep your text reply short and do not repeat every item from the card.
