My puppy has horrible diareaha help !?

My 3 month old puppy has terrible diareaha she hasnt taken a normal poop in probably 2 weeks I can't handle it anymore at night I put her and my male both in my back Room with the fence up when I wake up in the morning it looks like somebody just dumped pudding everywhere or coco wheats some mornings the puddles are the size of a small pillows . If I take her for a ride in the car she jumps in the back and let's it go again ! It's never solid or normal it's green and just diareaha . It can't be the food bc my maleis three weeks younger and there both huskies . He is pooping fine . Any answers will help . Thanks .
