Serena Williams was devastated after her pet dog Jackie passed away on Tuesday. Calling her four-legged friend her "angel", Serena paid an emotional tribute to Jackie on Instagram.
The tennis ace, who is currently ranked number one in women's singles, got her pet dog when she was 17 – just two weeks before she won her first Grand Slam in 1999.
Little Jackie accompanied Serena to various tennis matches and even modelled with her on photoshoots.

"Today really is hard for me," wrote Serena. "My special friend whom 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.

"Thank you for the kindness and joy you brought us," she added
Earlier that day Serena had explained on Snapchat that Jackie was ill.
"She's an amazing, amazing dog and I love her so much," said the Wimbledon champion. "She's getting old and she's really struggling. She means the world to me and she's made my life better."
