P!nk's Painful Tribute to Departed Doggie

P!nk will never forget her recently departed pooch -- especially since she inked his furry little face on her arm!

In late January, the singer returned home and found her beloved bulldog, Elvis, drowned in her backyard pool. The dog often took a dip but somehow didn't survive his last one.

The devastated songstress is an animal lover and supporter of PETA. Her body art memorial marks tattoo number 22. Elvis was a gift from Lisa Marie Presley.
