Jackson has been doing well with the potty, when we are not home he uses the diaper pads, and usually asks to go outside when we are home...but occasionally if you are not paying 100% attention to him he will eliminate on the floor, bed...wherever he is. It's almost as if he is mad at us. We have decided to get him a litter box to use. Do these work for dogs? I am afraid he will drag the litter all over the house to play with. Will he become dependant on it? I'd like him to be able to do both. Any suggestions or comments?
