Fiona Apple is postponing her South American tour to be with her ailing pup, Janet. The news was announced on her website today, via a posted a four-page, handwritten letter—written last week—detailing the relationship she's had with the 14-year-old pit bull since she discovered her as a four-month-old puppy in an Echo Park dogfighting ring in Los Angeles. Writes Apple:

Janet has been the most consistent relationship of my adult life, and that is just a fact.

We've lived in numerous houses, and jumped a few make shift families, but it's always really been the two of us.

She slept in bed with me, her head on the pillow, and she accepted my hysterical, tearful face into her chest, with her paws around me, every time I was heartbroken, or spirit-broken, or just lost, and as years went by, she let me take the role of her child, as I fell asleep, with her chin resting above my head.

She was under the piano when I wrote songs, barked any time I tried to record anything, and she was in the studio with me all the time we recorded the last album.

Janet currently suffers from Addison's disease and has a tumor in her chest, which is believed to have her close to death. "I know that I will feel the most overwhelming knowledge of her, and of her life and of my love for her, in the last moments. I need to do my damnedest to be there for that," Apple says. In a current market of quick turnarounds and the consistent expectation of live performances, the decision to put the relationships of those she loves before her career is completely respectable. That we get to read her thought process, as well as the intimate account of nearly 14 years together, feels like a privilege.

Enjoy that tilapia, Janet.
