The footage was uploaded online and has now gone viral.
According to the Daily Mail, Bella's owner said that she "has a fascination with splash water, she just watches the splash and even barks at it".
He added: "When I got into the water she watched me like a hawk. My wife noticed when I went under the water she would go nuts and start barking.
"Based on her reactions we thought she was afraid the water was hurting me."
The dog gets a huge cuddle from its owner when she leaps into to protect him.
The video was shot in Little Rock, Arizona.
