NEW YORK (AP) - Martha Stewart's dog Paw Paw, who was a familiar face on her television show and in her magazine, has died of renal failure.

The 60-pound chow, whose full name was Kublai Khan Paw Paw Chow Chow Chow, was almost 13. Stewart had owned him since he was born, and had named him Paw Paw for his large paws, a spokeswoman said.

"Paw Paw was a spectacular chow and an even more spectacular dog," Stewart wrote in a blog post on his death Saturday. "He was always my loyal companion, displaying the most agreeable temperament."

Stewart wrote that Paw Paw was a willing model for the camera, appearing in television commercials and national print ads. She said in his final days, he stopped eating and drifted off into deep sleeps.

She has two other dogs, Sharkey and Francesca, along with several other animals, including cats, horses and donkeys, at her home in Bedford, N.Y.
