He reminds me a little bit of Mikey, be still my heart, I LOVE beagles. I am so sorry you had to give him up, let alone only for him to disappear. They are little Houdini's with that nose of theirs, mine's only half beagle (might as well be full!) but I can tell! He could have very well just followed his nose and found another good home? You can hope! Maybe one day you'll see him again.

He's so good looking and handsome. Was he by any chance micro-chipped??
