I have my pup confined to the kitchen (with a tile floor) as he is too unpredictable in the bathroom department. The back door is 1 (carpeted) room away from the kitchen. I have been taking him out often and he is good about going outside and I think he understands the command "make" however he will still go at will when in the house without really any warning and once he is set on it nothing can distract him so that I can take him out. Some people use a bell and ring it when they take him out however I can't do this as he would just think it was a toy and play with it defeating the purpose. How do you suggest I teach him to communicate to me that he needs to go out?
