[Highland Park] Looking for an apartment

Hi. My name is Sean and I am looking for an apartment for my dog and myself. My budget is $400/month+util, and I would really like to try to stay in the Highland Park/Morningside area but I would also be open to a place across the river around Shaler, Sharpsburg, Aspinwall, and the Fox Chapel Area. I am 28 years old, I work full time in construction, and go to school part time working on my degree in Elementary Education. My dog is a 9 year old, friendly, black lab name Boo. He is well trained, well mannered, and quiet. We are looking for a place starting anytime between now, and April 1st at the latest and are willing to live with roomates as well. If you know of anything, please email me back. Thanks for your time, Sean
