Kaley Cuoco recently shared an emotional tribute after saying goodbye to her beloved dog, Blue.

She revealed that she cried harder over Blue’s passing than she had in a very long time. She remembered him as a protective and loving companion who watched over the  family and their other dogs

“Blue, it was an honor to be your second favorite human,” Kaley wrote in her heartbreaking tribute.

Tom also responded with a short but emotional message, expressing his love for Kaley and reflecting on the special bond between people, animals, and  children.
