Hello, this is my first post but I have visited this site many times. I have a 6 yr old male Doberman (Dante) and he has recently done something very strange. I was wondering if someone could provide me with some insight! Dante came to my family 4 yrs ago from a very neglectful and stressful environment. He's now absolutely amazing, with very few "issues" (aside from never wanting to leave my side....but he is a Doberman!). Anyway, he has always slept in a dog bed on the floor of our bedroom for the past 4 years. However, for the past two nights he has refused to go into his bed at night (he will during the day) and instead, he is going into a sunroom off of our bedroom and sleeping on a sofa. He's had access to the sunroom since we brought him home and he has never gone on the sofa in that room. Any ideas as to why he would suddenly change his bed? Thanks!!
