When he rings the bell, cut his leash and take him to the spot 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 doesn't, bring him right back in. Over time, your dog will learn that ringing the bells means the door opens and he can go outside to relieve himself
