Dwayne "The Rock" Johnson took to social media on Tuesday to announce that one of his two newly adopted French Bulldogs, Brutus, had to be put down after eating poisonous mushrooms, according to US Weekly.

The "San Andreas" actor shared the heartbreaking news on Instagram with a picture of him holding his beloved puppy. "Another reminder we have to live and love as greatly as we can today, because tomorrow is never guaranteed," the caption read, according to People.

"At approximately 11:15pm last night myself and @laurenhashianofficial had to make the painful decision to end Brutus' suffering by taking him off of life support and sending his soul to pup heaven. I held his lil' paw as he was finally at peace."

"As all puppies and dogs do, he ate a mushroom while playing outside with his brother Hobbs. This mushroom happened to have a lethal toxicity and within hours it was rapidly destroying his liver and immune system to the point of no return," he added. "I encourage all of you out there to be mindful of mushrooms in your yards, parks or anywhere outside your dogs play. What looks innocent, can be deadly to your lil' family members."

"We'll always love you Brutus ... and you'll always be my lil' main man and rough housing Brute," Johnson said, along with the hashtag #RIPBrutus and #WishICouldveSavedYouOneMoreTime, which refers to earlier this month, when the former wrestler rescued the two pooches from drowning in his family pool, as HNGN previously reported.
