Instructions
Punish the dog for leaving droppings in the house, and make sure the dog knows why it is being punished. Show the dog the droppings, and let the dog know you are upset. Don't hit the dog; a strong tone of voice and confident body language are more effective. Put the dog outside or in its kennel for a few minutes.
Be stern and exact in your interactions with the dog. Let the dog know that you are in control and that you disapprove. According to "Cesar's Way: The Natural, Everyday Guide to Understanding and Correcting Common Dog Problems," by Cesar Millan, "If you don't become your dog's pack leader, he will assume that role and try to dominate you."
Reward the dog when it goes outside rather than inside. Give the dog a treat on such occasions so it will develop a positive association with going outside.
Respond quickly when the dog comes to you and asks to go outside. The dog can't be expected to wait until it's a convenient time for you.
Get the dog used to pooping outside. Take the dog on walks and/or let it out for short bathroom excursions on a regular schedule.
Clean up after your dog when you go on walks. Bring a plastic bag or a plastic glove to pick up the droppings, then dispose of them properly.
How to Stop Dog Droppings
Anyone who owns a dog knows the joy of having a pet that loves you. However, there can be occasional downsides. For a number of reasons, a dog may decide to do its business in the house. The dog may not have received proper housebreaking training, it may be left inside too long without a chance to visit the yard, or it may be punishing you because it is unhappy with something you are doing. This problem can usually be solved with proper training, a regular walk schedule and making it clear to the dog that you are the boss.
