There's a window between picking up your puppy and the first vet visit, and the money moves fast. Between the adoption fee, the crate, the initial shots, and the chew-everything phase supplies, you're looking at a real hit in a short stretch. Spring is when most litters arrive, so breeders and shelters get busy fast and the popular ones book out early.
The trick is knowing what to pay for now, what can wait a week, and how to stretch the bigger charges across a few months so nothing knocks you sideways.
One honest catch: the 0% for 18 months on purchases is a deadline, not free money. If a balance is still sitting on the card when month 19 hits, interest starts adding up on the whole remaining amount, and it goes back to the regular rate. So the plan only works if you treat the $138.89 like a real monthly bill until the balance is gone.
