Oprah Winfrey is dedicating her Friday talk show to her cocker spaniel Sophie, who recently died of kidney failure at the age of 13.

"Sophie gave me 13 years of unconditional love. She was a true love in my life," Winfrey says on the show, according to a transcript released to the Associated Press.

Former View co-host Lisa Ling delivers an investigation on puppy mills — a segment Winfrey says is a must-see "for anybody anywhere who loves a dog, has ever loved a dog or just cares about their basic right to humane
treatment."

Winfrey — whose three current dogs are adopted — says she plans to adopt from an animal shelter in the future after seeing the segment.

"I would never, ever adopt another pet now without going to a shelter to do it," she says. "I am a changed woman after seeing this show."
