Create a bold outline body shape for a coloring book page for kids of a cute Brazilian Mastiff dog, walking with a boy and girl in a beautiful park with trees and flowers. The Brazilian Fila's tail can be gently wagging. The outline should be in bold black lines in a very white back ground, no shadow, and very clear for a coloring page for young children . The image should be only in black and white. Remember to keep the lines bold and clear, the shapes simple with a very white background to make the images accessible for young children, --ar 17:22 --s 50
