If no one wants it, you can put it on this site. Lots of people have problems getting rid of pianos and I guess this site finds people can use them.

Cute pups. Check again, I am pretty sure there is a no kill shelter there. We adopted from them in Houston county but can't remember the name. I can check with the wife if needed. Good luck buddy and good on you for helping them out.
