 Mighty’s on the other side now. After 7 days of searching from sunrise to sunset and into the wee hours, today, the 7th day ~the number of completion~ we found his collar... I have wept more this week than I thought possible, which has been very cathartic and healing... I left no stone unturned, crawled thru all the man holes, under the roads, searched every back yard and creek bed. Had two separate sniffer dogs do their best as well. I feel so grateful to have learned from my little Mighty man that love is eternal and the true meaning of devotion. I feel sure he was looking down on me whistling in every back yard and knowing that I was doing all I possibly could to respect our bond. He was more than a companion. It was a soul connection for sure. I’m sorry. I love you. Thank you. RIP my MIGHTY HEART my little fellow A ♠️’s ️Thank you to the community for allowing me to search through their yards for him and supporting my midnight walks. It was reassuring to see the best of people even in the worst of times. To the angels of @dogdayssar I’m forever in your debt. You ladies are heaven sent. Lastly thank you to @scottcampbell for the ink. I love you brother️l A post shared by  Orlando Bloom (@orlandobloom) on Jul 21, 2020 at 11:19pm PDT

Search And Rescue

In his lengthy post, the "Lord of the Rings" actor also recalled the grueling search that he did to find Mighty.

"After 7 days of searching from sunrise to sunset and into the wee hours, today, the 7th day ~ the number of completion ~ we found his collar... I have wept more this week than I thought possible, which has been very cathartic and healing," he wrote.

Bloom went on and shared that he "crawled through all the manholes" and searched "under the roads, every backyard and creek bed" and even had "two separate sniffer dogs" to track Mighty. Unfortunately, he was informed that his dog was found dead.

Despite the devastating news about his beloved canine companion, Bloom also said that he felt "grateful to have learned from" Mighty. He emphasized that his dog showed him "the true meaning of devotion."

"I feel sure he was looking down on me whistling in every backyard and knowing that I was doing all I possibly could to respect our bond," the actor furthered. "He was more than a companion. It was a soul connection for sure. I'm sorry. I love you. Thank you. RIP my MIGHTY HEART my little fellow A ♠️'s."

The "Troy" star then thanked his neighbors for allowing him to search Mighty "through their yards" and supporting his "midnight walks." He pointed out "it was reassuring to see the best of people even in the worst of times."

The soon-to-be-father of two also showed his deepest appreciation to Dog Days Search & Rescue -- a California-based animal search and rescue organization who helped him in the search.

Mighty is Bloom's adopted Labradoodle, whom he got in 2017. Coincidentally, it was the same time his fiance Katy Perry adopted an almost identical doggo.

Meanwhile, the 35-year-old pop star also shared the actor's post on her Instagram and said: "We'll miss our little buddy boy, Nugget's brother so much. Forever a paw-shaped hole in our hearts."

Aside from Mighty, Bloom had a rescue dog named Sidi.

The bonafide dog lover got the badly injured canine while filming a movie in China. The British actor rescued and took Sidi to the vet to attend to get the urgent care she needed.

The adopted dog became Bloom's best pal for 12 years until her death in 2016.
