Should I be upset?

My roommate expects me to dog sit his dog. Now his friend has dropped off a dog without my knowledge which is growling at me from inside a cramped carrier. The roommate comes home, rants at me for not taking the dogs outside enough, then sets the oven on self clean and leaves the house. I smell smoke and go into the kitchen. The entire house is filled with smoke from the oven and the alarm is blasting. I herd the dogs into another room and open EVERYTHING plus three fans to get rid of the smoke. It's pouring out of the house as if it were on fire. I call the roomie and he says, "Well I tried to tell you about the alarm, but you were in your room". How is this my fault? This among MANY things and little insults he has thrown my way. I am very low key and quiet, working in my room. This feels like the last straw to me. I didn't sign up for this. Nothing about dog care or being accused of everything under the sun in the rental agreement. What are your thoughts?
