Forever young

A grey wolf with wide eyes and a black nose peeks from behind a tree in a dark forest, then steps out and looks around with a nervous expression. A red dog with a black muzzle and floppy ears stands in the forest holding a coiled rope, looking up with wide eyes and a worried expression. The wolf reappears behind the tree, then steps out again, repeating its cautious movements. The dog remains in the same spot, holding the rope and looking up with a worried expression. The scene is set in a dark forest at night.
