*Serena Williams is in mourning today following the passing of her beloved dog Jackie.

“Today is really 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 wrote Tuesday in an Instagram post featuring a collage of photos with her late pooch.

“She was 16 years young and up until a few days ago was still sprinting,” Williams wrote. “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.”

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.
