Serena Williams mourning death of beloved dog

Tennis superstar Serena Williams has been left heartbroken following the death of her beloved pet dog on Tuesday (24Nov15).

The sportswoman took to Instagram to share photos of 16-year-old Jackie as she paid tribute to her "special" furry friend, who had been by her side since she was 17.

"She was 16 years young and up until a few days ago was still sprinting," the 34 year old writes. "Her poor body gave out this morning and she had a way of telling me it was time for me to be brave and let her go. With my dad by my side, we were able to say a loving goodbye.

"She was with me from 1999 until today and I miss her so much. I got out of the shower this afternoon and she was not there to lick my leg as she always did every day to remind me how much she loved me. I feel so lucky to have such a special friend. #breakingheart... Jackie Balla Pete Williams I will miss you and your memory will live forever."
