Solution to the River Crossing Puzzle with Dogs

Begin by recognizing the constraints: only one animal can be transported at a time, and certain pairs of animals cannot be left together unsupervised. Start by moving the smaller animal first, ensuring it remains safe while others are being transferred.

Next, focus on moving the larger animals in such a way that prevents conflicts. Each time you move an animal, ensure the remaining animals can be left together without any issues, like the predator and prey situation.

Finally, double-check the sequence of moves before completing the transfer. This will help ensure no mistakes are made along the way and all animals are safely relocated. The solution requires careful planning and logical thinking to avoid pitfalls.
