I am using this as a whelping box right now.  One of our puppies managed to get out of the plastic kiddie swimming pool that I had been using, so I had to look for an alternative.  I wish I had started with this pool instead.  Also, on Etsy, you can buy whelping pool liners for added comfort & cleanliness during the whelping process!  I am loving this pool, and will use it later as a pool or bathing tub.  Great quality!
