On hot days in the summer, I fill the kiddie pool so my pigs can swim. I float some grass around in there, and make a brick patio for a shallow end. In the deep part, I put cinder blocks for an island. Two of my pigs love it and will jump off the cinder block into the water, and push grass to the shallow part to eat it. They like it and when they are done we dry them off until they are 98% dry and then put them in their covered outdoor play area to popcorn off the rest of the 2%. My pigs like water in the pool, but they hate baths! LOL
