How to Get a Dog to Poop in a Designated Spot?

First, decide on the spot for the dog’s fixed toilet area. If you want the dog to go indoors, prepare a pet-specific small toilet; if you want it to go outdoors, walk the dog at fixed times and places so it learns when and where it can relieve itself. Next, each time you walk the dog, take it to the designated spot and let it stay there until it defecates.

Finally, whenever the dog defecates in the designated spot, immediately reward it, for example, give it a small treat or praise it happily, to encourage the dog to repeat the behavior.
