How do I keep my new puppy from pooping in our dining room? I yell at her and show her what she did wrong but she continues to do it.?

Don't yell at her when she does it. Grab her and take her out and walk around with her. She has zero idea why you're yelling at her.

& she doesn't understand one word your are saying. Yelling won't work, sticking her nose in it won't work.

You need to learn how to house break her. There are thousands upon thousands of site online about dog training, any kind, & there are thousands & thousands of books written on dog training. & you want us to put it all in this tiny little space? Can't do it.

You need to learn how to go about teaching a dog to go potty outside. Many ways to go about it, just need to find the method that works best for you, your dog & your living conditions. You also need to teach it basic obedience, 7 basic commands. Can be learned in an 8 week course.

to find more information on potty training/house breaking a dog, look up, 'how to house break a puppy' & 'how to potty train a puppy'?

Raising a puppy is hard work. But you got the dog & now you are committed.

Stop "yelling at her"! Puppies don't come trained that's your responsibility.

Constant supervision, contain only when you can't, immediate correction when caught in the act, not after the fact, supply sufficient daily elimination times outdoors, every 1-2 hours, 30-40 minutes each time.

Training requires a lot of patience, consistency, diligence, time, regardless of weather conditions, how you maybe feeling (tired/sick/busy), and other obligations such as school, homework, extracurricular activities, childcare (if applicable), household chores, work and social life.

Once trained you must still enforce what was taught on the daily basis for the life of the dog, 12-17 years.

Proper feeding may help determine elimination times.

Best way to get them to do there business out side is to simply grab there poo and put it outside where u would like them to go to the loo, I know it sounds fairly unsanitary but when they next go outside they will pick up the cent and feel the need to do there business there from now on, (this worked with my maltese when he was Pissing and pooing in out kitchen :/ )

If you put a bullet in her head, she will never do it again

wear a diaper for her.

Is there any chance she has worms? Something that may work is blocking her out of there or maybe deep cleaning the floor.
