There are few things worse in life than the passing of a beloved family pet.

Unfortunately for NASCAR Sprint Cup Series driver Kyle Busch and his wife, Samantha, that is what they are experiencing now.

Samantha Busch took to Twitter to offer a sweet good-bye to one of their dogs, Kelly, and we offer our condolences as well.
