I do this all the time, for a friend I met online who rescues elderly Shelties. I follow her & all the Shelties on facebook regularly. These are doggies who wouldn't get a chance, otherwise, as they're all old (obviously) and many of the have health issues. Manageable ones, but ones that would make them *highly* unlikely to be adopted otherwise. These sweet little dogs get to live another year, or sometimes two or three, sometimes even more that they otherwise wouldn't have. And very happy & comfortable extra years, at that!
I figured the food sent would be a charitable deduction as well. My friend does have that 501c status, or whatever it's called ~ I probably typed a kind of Levi's. Official charitable organization status. Heh. : )
