About this puzzle
Dog 40x40 Nonogram sits in the dog theme as a hard 40x40 picross board. 511 of its 1600 squares are filled, so it reads as a fairly balanced grid at roughly 32% coverage.
The biggest single run here is 22 cells long — fill that first and the surrounding lines fall into place faster. Expect to spend roughly 25 minutes from a blank grid to the finished picture.
How to solve this nonogram
On a large board, divide it into zones: lock in the longest clues, mark proven-empty cells with X, and only then chase the tight lines. With balanced coverage, alternate between filling forced cells and ruling out empties to keep both kinds of clue moving. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.
