Just The Facts : Did Will Smith get to keep the dog?

Will Smith is one of my favorite actors of all time.  If you haven't seen "I Am Legend", essentially it's a post-apocalyptic world where he's the only person left.  Him, and his dog, played by a pooch named Abbey.  There's one part in that movie, which I don't even want to think about, which makes me cry every time I see it.  It also makes me a bit teary-eyed when I hear the song "Everything's Gonna Be Alright" by Bob Marley.  If you've seen the movie you know what I'm talking about.  Will fell in love with Abbey while filming the movie, and he even wanted to adopt her, but did he get to?..
