I have a 1-year-old female husky and live in a house with my girlfriend. She works from home and I'm in the office most of the week, so she does most of the dog duties while I am gone (feeding breakfast and dinner, walking, potty, etc.) On the weekends I take over as much as possible, but over the past several months the dog has stopped pooping for me. She will pee just fine, but then will wander around (leashed) sniffing things and trying to eat leaves and grass and will not poop no matter how much I try to encourage it. I've even tried walking her around the yard a few times to work it out but still have no luck. My frustrated girlfriend will then take the leash from me, do nothing different than what I did, and within a minute or less the dog has pooped.
The only thing we can think of is that she doesn't respect me for some reason, but I don't know how to fix that because I feed her 2-3 days out of the week when I'm home and I play with her daily. What is causing this behavior and how can I fix it?
