Dwayne 'The Rock' Johnson Shares Heartbreaking News About Puppy

— -- Dwayne "The Rock" Johnson is mourning the loss of his puppy Brutus.

In a heartbreaking post on Instagram, Johnson informed his fans that he had to put his French Bulldog puppy Brutus down on Monday night, after the puppy ingested poisonous mushrooms.

"Another reminder we have to live and love as greatly as we can today, because tomorrow is never guaranteed," wrote Johnson.

"At approximately 11:15 p.m. 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," Johnson wrote.

The news comes just weeks after Johnson saved Brutus from drowning in his family pool.

Johnson explains that Brutus ate a mushroom while playing outside with the wrestler's other puppy, Hobbs, but unfortunately, "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."

Johnson thanked the "incredibly caring" nurses and staff at The Animal Medical Center at Cooper City for doing everything they could to try to save Brutus, and he warned dog owners to be mindful of mushrooms in "yards, parks or anywhere outside your dogs play."

"We'll always love you Brutus," wrote Johnson, "And you'll always be my lil' main man and rough housing Brute."
