More: I think Musa is a perfect example of what a senior dog can be. At 17, she is still determined to live her best life. There is no stopping this free spirit. Even now, after her battle with cancer at 16, a inner ear/neurological disorder and facing down her kidney disease, at the age of 17, this most recent photo says what she thinks of it all that. The water is just fine! Some days it seems nothing is going to stop her - she cannot live forever but she lives up to her name Musa, little Muse, sheer inspiration and a lesson of what the love of living life can do.
