<human>: Give me the gist of the text in a nutshell

My roommate just got a dog, about 1.5 years old and a pound pup. He is so sweet to her and strangers but very wary around me. Normally I would be okay with this as I am not a very big dog person, however I have a job where I work from home and my roommate is gone all day at work, leaving me with him. At first he would howl while she was gone and it was heartbreaking. I want hime to feel comfortable in the apartment because he lives here too and I don't like that he sits in her room and pouts all day when he is welcome to explore the whole house. I have taken to leaving my door open and making sure he knows I am not threatening. Is there anyway I can show I am loving and non threatening?
<bot>: roommates dog is skiddish and won't come close to me. How do I show him I love him?
