Thanks but I'm afraid she may not be here much longer

She's 12 years old, is allergic to most native pollens (since birth), totally deaf, and has recently been diagnosed with tumors in her breasts. On top of that, she's allergic to penicillin (which most of her allergy meds are made from). And yesterday I had to take her to the vet cause she hasn't eaten anything in a week and is hardly drinking.

On the bright side, I've had 12 years of unconditional love. Am I scared? You bet! She's been my best friend, my confidant, and my co pilot when I drove trucks. I know I'm gonna be a basket case when she goes but I plan to have her cremated and use the ashes to tattoo her portrait on my leg, keeping her with me always.
