Often I think people fuss over their pets too much, but keeping one for 16 years should warrant some mourning.

Grand Slam Queen Serena Williams recently lost her dog, named Jackie, apparently to old age. Williams has had the canine since she acquired her at the age of 17- just prior to beginning her journey to become one of the greatest tennis players of all time.

On her Instagram, Williams kept fans abreast of her Jackie’s fight, and her eventual capitulation. It was a sad moment for the star, who wrote tribute after tribute for her dog.

“Today really is hard for me. My special friend in which I got at 17 (2 weeks before I won my very first Grand Slam) left me today. She was 16 years young and up until a few days ago was still sprinting.” she wrote in one post, with several photos of the two of them together.

RIP?

Today really is hard for me. My special friend in which I got at 17 (2 weeks before I won my very first Grand Slam) left me today. She was 16 years young and up until a few days ago was still sprinting. 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 everyday to remind me how much she loved me. I feel so lucky to have such a special friend. Give your dog, cat, pet a big hug. #breakingheart #bff Jackie Baila Pete Williams I will miss you and your memory will live forever.
