Oh he sound perfect ! I wish I lived closer, I would take him in a flash. He could live on our 22 acres and play with my two hounds all day long. I rescued a little beagle/basset X and spent alot of time getting him to trust and love me so I now how you must be feeling haveing to give your baby up.
I believe he will find an amazing loving home. Good Luck and Best Wishes in finding the perfect home.
