how to stop dog pooping in the kitchen ?

You have to housebreak the dog.

Crate and supervise - put on a feeding schedule to regulate the bowels and have set times for the dog to go out and do its business.

You need to train the dog and give it ample opportunities to go outdoors and empty.

This may sound mean, but the dog needs to know who is control. A light tap to the nose with a rolled newspaper doesn't hurt the dog. It just lets the dog make a connection. Another thing to do is take the poop outside to demonstrate that that is where it is supposed to be. Canines aren't as smart as people believe they are. They know only basic things and rely upon hierarchy for structure. They actually require you to be the boss to understand their place in the world and be comfortable. You don't have to be mean, just assertive.

Try This- I trained my 3yo chow chow Pluto to stop pooping in the kitchen in just 5 days. It can be done, dont listen to all the naysayers. I wish we were faster to discover the Dog discipline magic system i found with google.
