OH I FEEL YOUR PAIN.
My ex-husband and I lived with his parents and they were horrible with my dogs and worse horrible TOO my dogs.
They always talked about their Shih Tzu who had passed and were always saying how he NEVER had accidents and how perfect he was and my ex-MIL actually said to me that she didn't like the way I was raising my dogs...UGH
Now you know why they are all EXES!!!!!!
