Meghan Markle is mourning the loss of her beloved dog, Guy.  the Duchess of Sussex, 43, announced the death of her beagle on Instagram after her return to social media.

Meghan adopted Guy back in 2015 from Ontario, Canada’s A Dog’s Dream Rescue, and the rescue pup has been with the royal from her days on Suits through her engagement and marriage to husband Prince Harry, and even the birth of their two children — Prince Archie, 5, and Princess Lilibet, 3. Guy even makes a cameo in the new trailer for Meghan’s upcoming Netflix series, With Love, Meghan, appearing beside her on his bed in the kitchen.

“In 2015, I adopted a beagle from a dog rescue in Canada. He had been at a kill shelter in Kentucky and given a few days to live. I swooped him up….and fell in love,” Meghan began her Instagram tribute. “They referred to him as ‘the little guy’ because he was so small and frail, so I named him ‘Guy’. And he was the best guy any girl could have asked for.”

She continued, “If you followed me on instagram back in the day, you saw a lot of him – and on The Tig too. He was with me at Suits, when I got engaged, (and then married), when I became a mom….he was with me for everything: the quiet, the chaos, the calm, the comfort.”
