There are a few factors that determine how long it takes to solve a dog and cat puzzle, such as the puzzler's skill level, the piece count, the complexity of the design, and how many people are working on the jigsaw. Puzzles with fewer pieces--such as 300 or 500 pieces--will take two to five hours on average, while puzzles with 1,000 pieces or more can take much longer.
To make your puzzling experience more enjoyable and save time, consider using a puzzle organizer and other accessories, like a dedicated puzzle table. You can also use a puzzle strategy when tackling larger cat and dog puzzles--organize pieces by color at the start, build out the border first, and work in sections.
