Cass,

You did your best. Don't feel bad about that! You have to think of what is best you and your current furbabies. Labs (from the looks of it, he's got some in him) are pretty hyper dogs and need alot of attention. You gave it your best shot. Things happen for a reason. I know you'll find him a great home. And don't worry, YOUR doggie will come along when the time is right.

Hang in there!

(((((hugs)))))
