<human>: My roommate just got an 8 month old besenji-shiba mix from an adoption agency. The dog is sweet as can be but is wildly untrained. She isn't even house broken (is this normal for 8 months??). She constantly goes pee and poop in the house (20+ times and counting!) and shows little or no shame after being yelled at.

One time after peeing in the house the dog owner didn't make any moves to discipline the dog so I decided to take matters into my own hands. I wanted to discipline the dog by showing her the pee puddle so I grabbed her collar to point her head in the direction. I was very gentle at first but when she flopped to the ground in order to avoid being disciplined I snapped and began dragging her across the floor to the pee puddle. As soon as I started doing that I was being yelled at by my other roommates to let her go, so I did immediately and stopped what I was doing. I apologized to the dog owner for doing that after I calmed down.

I realize that I shouldn't be disciplining other people's dogs but having a sanitary house is important to me. I didn't think much of this incident but the other day the dog's lack of house training was brought up in conversation and I said that the dog hasn't been peeing in front of me as of late. Then the dog owner said under his breath, "Thank God." Was I way out of line? How do I make this better with my roommate and his dog? Or am I just over analyzing this situation? Thank you for your help, Reddit!

Can you condense the text into a few key points?
<bot>: I disciplined my roommates dog for peeing for the twentieth time in our house in front of him.  Was I out of line?
