What truly makes Dwayne "The Rock" Johnson a great guy isn't all that brawn, but the big heart beneath it.

In the holiday spirit of giving, the wrestler-turned-actor helped save an abandoned puppy's life by donating $1,500 toward its life-saving surgery. And he's never even met the pooch.

Actress Michelle Trachtenberg tipped Johnson in a tweet last week that the ailing puppy — named Dwayne “The Rock” Johnson — was in desperate need of financial aid, Pix 11 reported.

The 4 month old had been dumped at North Central Shelter in Los Angeles with a large metal wire wrapped around his mouth. Once the wire was removed and 17 stitches were put in, the pup was taken in by Saving SPOT, a rescue organization that gave him his celebrity name.

The group also launched a GoFundMe page to pay for his medical care.

Along with the wire ordeal, it was discovered that Dwayne the dog also had a dangerous heart murmur and needed a cardio exam.

"Once we know exactly what is wrong with his heart: we will either fix it surgically or treat it with medication," Saving SPOT said in its plea for funds.

In stepped "The Rock" himself!

The “Ballers” star retweeted Trachtenberg's plea and then followed up by dropping $1,500 into little Dwayne’s digital doggy bowl.

“Stay strong lil' Rock! Let's get you taken care of, healed up and feeling better for Christmas. Plus you have a VERY cool name to uphold;). Got your back,” the "Furious 7" actor wrote on the page.

The magnanimous gesture shouldn't surprise fans of Johnson, a guy who wears his heart on his muscle-popping sleeve.

But it’s especially moving considering the tragedy he and his girlfriend Lauren Hashian recently endured.

Just a few months ago, their French Bulldog puppy Brutus had to be put to sleep after eating a poisonous mushroom.

By helping another puppy live, Johnson may just be helping himself heal from the loss of little Brutus.

Meanwhile, the effort for his furry namesake has now surpassed its $5,000 goal by $1,000.

Saving SPOT has said that any funds that are raised and not used for Dwayne will go to the more than 60 dogs provided for by the organization.
