There is only one way to teach a boxer to swim. You must don a thick top ( to avoid getting scratched) and you must carry the boxer into the water and hold it under the tummy while it flails and scratches you, its legs churning wildly !!! After your back is broken and your body resembles a tiger attack your boxer will have a marginal idea about the mechanics of swimming. Eventually , after many lessons , your boxer will simply swim away from you, towards the middle of a great lake , in hot persuit of an irate swan family. After you have swum out to rescue the boxer, towed it back to shore and congratulated your self on your successful rescue mission, your boxer will leap into the lake again and robotically repeat this exercise!!! At the end of your long, hot, mosquito ridden day, as you slowly repack the car, your boxer will swim to the far side of the lake and dissapear into the undergrowth. After a lenghty , leg and face scratching search of the gorse, of which any boys scout association would envy,you discover your boxer has already returned to the car and is sitting on the drivers seat waiting! Who said dogs are stupid!!!!!:confused:
