Porthos is the adult male dog in the Roseland family, which appeared in the Pets expansion pack of The Sims 2 with his owner, Cyd Roseland and they can be found in the family bin. He considers Cyd part of his pack, suggesting a very close relationship between master and pet. Porthos appears to be based on the appearance of an American Pit Bull Terrier, with his square snout and perky ears. His undercoat is white and all four paws have white socks. The upper coat is black and covers only his back and a masking over his face and ears.
