But when she burst up, like a flame he hadn't anticipated, he yelped and tumbled back to the earth. This was happening far too much lately, it seemed. The momentum of suddenly pushing against something inmovable, to having it no longer there caused him to tumble and roll in the sand. He laughed loudly, this time it was his job to squirm and flail his paws at her.  "Im not getting in the water!" He said loudly, laughing as he attempted to keep her away with his flourishing legs, flopping this way and that way as he growled, snapping his jaws as he waited for her to make her move. And yet, his tail was a flourish, kicking up sand in his happiness. His muscles burned, his breath came out in pants, but he was happy.
