If you are going to continue with this swimming exercise just make sure the water is warm & that you have a warm blanket to dry the rat off with after swimming (pop a towel in the dryer to warm it up). Hairless rats have to work real hard at keeping their body temperature correct. If you chill them placing them in water that is too cold or allow them to air dry after a dip you could cause your rat to become rather sick.
