Gee -- a foot? Mine think two inches = a swimming hole. Perhaps it's because we are in NM and have nor real places to swimming on a regular basis.
The corgis that I have pet sat for only need a small puddle and they could be there playing in the water for hours if I had the time for it! Corgis are truly the funniest dogs I've ever met!
If its only a foot deep at least you can wade in and get them out! See Yea George xxx
There is a great youTube clip of a swiming corgi... just search "Corgi Flop" and you'll find it. :-)
