Doggy Paddle

　　Dog or doggy paddling is a kind of improper way of swimming. If you are doggy paddling， it means you have your head out of the water and are quickly moving your arms under the water in an effort to move forward. If you don't want to doggy paddle， you must keep your head under the water. You should only lift it to exchange breathes every couple arm strokes. A stroke is the movement your arm makes to move forward. Doggy paddling is a simple but slow way of swimming. Heather Pfeiffer

　　狗爬式

　　狗爬式是一种非主流的游泳方式。如果你使用的是狗爬式，那就意味着你得把头浮在水面，同时在水下拼命的划动手臂，努力将自己往前推。如果你不想使用狗爬式，你就必需将头埋到水里。在手臂每划两下之后，将头浮出水面呼吸换气。划水是你推自己前进的一个动作。而狗爬式虽然易学，但真正游起来会很慢。
