I have been reading all this with interest. I use this: Towelling Rug - Dog Coat
and have done for 20 years on cockers (english) springers, soft coated wheatens and now my golden. Once the side on the dog is wet turn it over and use the other side!! They send them to me in France so I should imagine they would post all over the world. Mine are now 20 years old and still going strong. They wash in the machine and dry on the radiator (not in a dryer). Also great for a wet dog after a rainy walk.
Really good for dogs that are afraid of the noisy dryer, or if there is no electricity (camping).
