Dolly is a supporting character, later antagonist in Jack London's 1903 short adventure novel The Call of the Wild. She was one of Francois and Perrault's sled dogs until she got rabies after getting attacked by a pack of wild huskies.
Dolly came with Dub and Pike to Francois and Perrault's sled team. And one night when the wild huskies attacked camp, Dolly's throat was torn, but she survived. After some time, Dolly became mad, and started howling like a wild wolf. She announced her condition by a long and heart-breaking wolf howl that sent every dog bristling with fear, then sprang straight for Buck. He had never seen a dog go mad, nor did he have any reason to fear madness; yet he knew that here was horror, and fled away from it in a panic.
He raced with Dolly straightaway, panting and frothing, one leap behind; nor could she gain on him, so great was his terror, nor could he leave her, so great was her madness. He plunged through the wooded breast of the island, flew down to the lower end, crossed a back channel filled with rough ice to another island, gained a third island, curved back to the main river, and in desperation started to cross it.
And all the time, though he did not look, he could hear her snarling just one leap behind. Francois called to him a quarter of a mile away and he doubled back, still one leap ahead, gasping painfully for air and putting all his faith in that Francois would save him. The dog-driver held the axe poised in his hand, and as Buck shot past him the axe crashed down upon mad Dolly's head.
- While she does exist in the 2020 adaptation, she never contracted rabies and still served as a supporting character.
- Her personality is also based on Bashful from Snow White and the Seven Dwarfs.
