The Rock mourns the loss of his puppy, Brutus

RIP Brutus.

Dwayne "The Rock" Johnson shared a heartbreaking story on his Instagram about his new puppy, who you may recall almost drowned just a few weeks ago. The French Bulldog had to be put down this week after he ate a poisonous mushroom, which The Rock said had "a lethal toxicity and within hours it was rapidly destroying his liver and immune system to the point of no return." With Brutus that sick The Rock 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."

He also had this tribute for the little guy:

"We'll always love you Brutus.. and you'll always be my lil' main man and rough housing Brute. #RIPBrutus #WishICouldveSavedYouOneMoreTime"

The star did take the opportunity to remind all his fans to take advantage of every single day they have, and to check their yards for bad mushrooms:

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