Fiona Apple took to her Facebook page to post a picture of a handwritten letter explaining that she must cancel her South American tour in order to spend time with her dying dog, Janet.

She wrote on her Facebook page that she and her fans there must meet at another time so she can spend as much time as she can with her almost 14-year-old pitbull. Janet suffers from Addison's Disease, which the singer says "makes it dangerous for her to travel since she needs regular injections of Cortisol, because she reacts to stress and to excitement without the physiological tools which keep most of us from literally panicking to death."

According to The Huffington Post, Apple was supposed to begin her South American tour in Porto Alegre, Brazil on November 27.

She was 21 when she found four-month-old Janet in Echo Park with a rope around her neck along with bites on her ears and face. She adopted her and Apple considers Janet her child since she says it's always been the two of them.

"I just can't leave her now, please understand. 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. Sometimes it takes me 20 minutes to pick which socks to wear to bed. But this decision is instant. These are the choices we make, which define us," Apple wrote.

She finished her letter to her fans saying, "So I am 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. I'll be seeing you. Love, Fiona."
