Fiona Apple is postponing the South American leg of her worldwide tour to care for her dying pit bull, Janet.

The dog and Apple have been together for 14 years — since the singer was 21 and the dog was four months old.

Apple says the dog she adopted had been used for dogfighting and was found with a rope around her neck and bites across her face and ears.

The singer made the cancellation announcement in a handwritten letter posted on her website.

The dog has been ill for the past two years, with Addison’s Disease and a tumor in her chest.

Apple describes Nancy as “the most consistent relationship in her life … She is my best friend, and my mother, and my daughter, my benefactor, and she’s the one who taught me what love is.”

“I just can’t leave her now, please understand,” she adds in the letter. “If I go away again, I’m afraid she’ll die and I won’t have the honor of singing her to sleep, of escorting her out.”

She concluded the note with these words: “I’m staying home, and I am listening to her snore and wheeze, and reveling in the swampiest, most awful breath that ever emanated from an angel. And I am asking for your blessing.”
