i think if ya have a smart dog they will try to correct the stupid ones sometimes. all my dogs have always pooped off the concrete in the grass. The newest addition liked to poop on the concrete i would beat her A$$ and rub her nose in it and she never seemed to get it finally one day i was yelling at her while she started to bow up on the concrete when my old gyp went over and tore her a new one...
now I dont think she poops at all you never see her anyway. Maybe she diggs a hole like a cat now
I am glad she was dog aggresive
