We adopoted a 3 year old puganese 3 weeks ago. I had him neutered and got all his shots. But after you take him out he comes back inside and poops? Help before my husband makes me get rid of him

He might need a lot of tender patience based on his past 3 years, which I assume you don't know about. Take him out on as long a walk as you have time for, and when he poops, praise him profusely. Keep doing this once a day (as well as several short pee trips) until he understands. Clean the spots he went in thoroughly and close off as much of the house as you can until he is housebroken. Take him out on a schedule. Dogs really like schedules, and it helps them do their business outside.
