AceShowbiz - Mandy Moore has suffered the loss of her loyal companion, Jackson, after over 14 years together. On Friday, November 1, the 40-year-old actress took to Instagram to express her grief and share cherished memories of her furry friend.

"My beautiful boy. Thank you for an extraordinary 14+ years," Moore wrote alongside a carousel of photos showcasing Jackson's life with her family.

Despite his protective nature, Moore acknowledged that Jackson had a unique way of showing love. "You weren't big on other animals or the kids, but you loved in your own way."

Jackson's gentle nature belied his protective bark, according to Moore. "You had a big bark that seemed to scare some folks, but you were actually the most gentle guy who was secretly scared of his own shadow."

Included in Moore's post was a selfie of her cuddling with Jackson on the couch, as well as photos of him interacting with her other pets and her three children.

"My Jackie D. My sweet old man," Moore concluded her tribute. "I hope you find Joni [Moore's late dog] and have a giant pool to chase tennis balls and swim until your heart's content. We love you forever."

Moore's friends and followers offered their condolences in the comments section. "Sending you and Taylor and the fam so much love," Minka Kelly wrote. "He was the luckiest to have you as his mama."
