Using a swimming pool net, carefully remove the frog from the water. The frog may be difficult to catch, but be persistent and try to corner it. Be careful not to injure the frog. Obviously, different rules apply to frogs that are already dead.
Rinse the frog in fresh, clean water. Don't use water that is hot or cold to the touch. Lukewarm water will safely clean the frog.
Relocate the frog to a safe place as far away from the pool as possible. You can place the frog in your garden, under a bush, in a pile of rocks, etc. Make sure there are no pets or other dangers nearby.
Install a mesh trip in front of the entrance to your skimmer. Frogs will not pass through the skimmer, though it may also block leaves and things that you do want in there. This is a temporary solution until you can install a Toadsaver.
Place a large flat rock on the pool steps that will allow frogs to escape after they wind up in your pool. Make sure it's just an inch or so from the edge.
Install a Toadsaver. These can be found at most pool supply stores. This apparatus will allow frogs to exit the pool immediately and will reduce the amount of chlorine they take in.
