The 43-year-old actor's pets decided to cool off with an impromptu swim over Labor Day weekend and that is when the unfortunate incident happened.
The San Andreas star posted an Instagram photo of himself holding up his two new puppies in the pool.
In the caption, Mr Johnson explained that he gave both of the French bulldogs a chance to explore his yard after bringing them home for the first time, and both quickly ran into the pool.
Here's a fun Labor Day weekend story... We just decided to add two new members to our Johnson family. Baby French Bulldogs. In my right hand is BRUTUS and in my left hand is HOBBS. Bring them home and immediately take them outside so they can start learning how to "handle their business and potty like big boys". I set them both down and they both take off in a full sprint and fall right into the deep end of our pool. HOBBS immediately starts doggy paddling while BRUTUS (like a brick) sink heads first to the bottom of the pool. I take off into a full sprint, fully clothed, dive in the pool, swim to the bottom, rescue my brick, I mean BRUTUS and bring him back to the edge of the pool. He was a little delirious.. took a moment, threw up all the water he swallowed and looked up at me as if to say, "Thank God you didn't have to give me mouth to mouth!" and then ran off to play with his brother. A few lessons I've learned today.. A) Not all puppies have the instinct to doggie paddle. B) Some puppies (like BRUTUS) will be so in shock by experiencing water they will sink extremely fast so react quick. C) While spiriting to save your puppies life, before you dive in, try and throw your cel phone to safety. Don't keep it in your pocket... like I did. #BRUTUSLives #HOBBSCanSwim #MyCelPhonesDead #AndNoMouthToMouthNeeded #HappyLaborDay
