I grew up with the most lovable German Shepherd/Collie cross. She was one of those you just had to pull out of the water. She also looked after us kids. Where we usually swam, there was a very gradual deepening of the water, but my granparents lived on a river where the water suddenly dropped to about 10 feet in depth, just about 3 feet in. She swam there, too, but we usually didn't. One day we did, and my 10 year old cousin was first in. Well, she raced down to the river as he approached it, and just as he was ankle deep, she arrived, and grabbed the back of his bathing suit with her teeth. He freaked, we laughed. She was saving him from the deep water. LOL Once we all got in, she got in and circled us like Momma Duck, just in case.... LOL
