More: Blu is absolutely the sweetest Hound , my first HoundDog … he was a rescue , when actually he rescued me as well ! I had lost my dad when Blu came into our lives . I was Blu in life and so was this precious Houndog . It’s been never a dull moment since . He makes me laugh with his lil sweet face an big personality! It was a joy to see him bloom , a know how much he’s loved makes him that much more confident and sweeter .
