As Lili's fingers brushed along Bart's head, she felt something odd. It seemed like small protrusions growing from his skull that hadn't been there before.
"Whats that boy...?" She asked and when she looked down at Bart, a thrill of horror went through her.
Two small black horns were pushing through the dog's skull beneath her fingers, and the fur around them was shifting, turning dark and wafting away as if being burnt, replaced by smooth, black leathery skin.
"B...Bart!" She cried, watching. The dog squirmed, his toes gripping intot he carpet as the leathery skin began to overcome his face. HIs eyes turned a dark, flaming red, and a second set of eyes opened up. HIs mouth flashed as fangs became larger, tongue becoming forked. More horns and spines began to grow as a thick mane of flames burst from his back, his tail becoming a spade. His claws thickened as his body bulked.
In moments where her old, friendly dog had been stood a huge, imposing hellhound. It growled....tail whipping behind it.
"Bart...bart no!" Lili screamed as it lunged at her....and then pinning her licked her face. Lili blinked. The hellhound Bart was treating her like any dog would treat its young master...
"Oh God Bart, what have I done to you..."
