Seems like manipulation on top of manipulation. She demands the dog or else. Then she gets emotional over her father's death so you will feel even worse while verbally abusing you. If you think about it, if DIL just lost a dear one, Making you go through the same type of a loss would be the last thing a human being would do. This lady is bad news. If she keeps pushing your buttons until you give, can you imagine her raising your grandchild if they stay together. Keeping you and your son and pug in my prayers.
