When he rings the bell, clip on his leash, and take him to the place where you want him to eliminate. Give him a few minutes, and if he does his business, praise and give him a treat. If he does not, take him right back inside. Over time, your dog will learn that ringing the bells means the door will open and they can go outside to relieve themselves
