Un-dessicate me!

Cold, dry, windy August seems to have dried out this little frog. Found on kitchen-yard tiles close to dogs' water bowl (in which they drown: can't swim). Tacky and impeded by dog fur when found (pic 2). Enjoyed palm-ful of water so placed in saucer in garden to 'drink' (osmote?) as much as it needed overnight.
My ring's 4 mm wide.
