We got Sir Dave in November 2008, he was not a very well froggy when we got him, and we were told not to expect him to live for much longer than January/february of 2009.
He battled through and was a happy little 'phibby part of our family until he lost his battle in the beginning of December 2009. He lasted months longer than was to be expected, we even got him to start eating without help at one point as well.
He croaked his last croak at the hoover in the middle of november, and hadn't done it since.
We will miss his loud protests at the hoover and hairdryer.
