My new nieghbor just moved in and she has this big cattle dog, she works midnights and sleeps all day and she?

she takes this big dog out to go to the bathroon and drags it back in, I feel so sorry for this dog, it never gets outside, one day I seen is spinning around trying to get the feces out as she rushed it and ran it back in, I want to call the humane society, but wonder is they would do anything?
