I have a five year old rottwieler and all of sudden he's been pooping in the house and he only poops one little poop... After taking him out and leaving him outside so he could do what he has to do and now he comes in and just poop one little poop... I don't understand he's trained I don't know what to do and I think he's doing it out of spite because went away for two weeks about month ago but my mother in law watched him he wasn't doing it then... We came back then my mother in law went away for a week and that's when he all of sudden start to poop one little poop... I don't know what to do.. When I finally took that one poop and ask him wheat's this he knows he did something bad and then I tell him out side and then I take him out side

Ask mom what she was doing with him while you were away. Maybe she gave him a treat or something and he's rebelling not knowing you don't know about the treat business. Or what else has been going on in your home lately? Have you been spending more time away from the house than usual? My Jack Russell likes to have me bring her a stuffed toy when I go out shopping and if I don't... then she can sulk for days at a time. And if I bring home a talking toy or one that makes prerecorded sounds she's my buddy for weeks at a time.

Just pointing out to him he should poop outside is okay and all but he's got other ideas and it's up to you the owner to figure him out. Could be something very simple that mom did.
