Dog Litter Training
Design the environment so that it is difficult for the dog to fail. Your dog wants to please you, and you can help him succeed. In this initial period, the dog should have only two location options: either with you, or a direct path to his bathroom area.
Soak a small bit of the dog's urine in a paper towel or newspaper and put in his bathroom area. If your dog smells his feces or urine in his bathroom area, he will be more likely to use that area. Clean any "accident" areas to an extreme degree so the dog doesn't smell his feces/urine there [you probably don’t want to smell it either]
Get the dog used to simply getting in and out of the box. This can be made into a fun experience for the dog. Simply lift and place the dog in the litter box and use a key phrase like "use the box". Praise him and be happy. After a few sessions, you should be able to have dog go in the box on his own when the keyword is used.
If you catch the dog in the act of going in the wrong place, you need to "shock" the dog. A loud "NO!", slapping your hands together, and sudden movement toward the dog should cause the dog to bolt. His destination must be his bathroom area. Once you and the dog are there, start praising the dog.
If by chance you see the dog in the act doing his business in the litter box, be beside yourself with joy and happiness!
Don't place the litter box near the food and water. Dogs don’t want to poop where they eat.
If you know when your dog pees or poos, take him/her to the spot. Hold them there for as long as it takes for them to do their business.When he/she is done give a treat.
It is best to litter train your dog while it is still young.
