Do i need a lawyer if an x tenant is claiming $5,040(1 yrs) of rent in small claims? ALL of her allegations are NOT true?

I had a person rent a room in my home for almost 4 yrs.There was no written contract,just a verbal agreement. Her claims against me are 100% false. She claims i harassed and denied her access to kitchen and bathroom, which I never ever did. Unlawful entry by landlord. She brought in two dogs and locked them in her room for over 10 hrs while she was gone. They were going crazy..yelping and scratching door so I let them out to take care of business. Also says i didn't provide peaceful quiet. NOT true! I was gone every day from noon til midnight and she had her cousin and boyfriend living here for the last year. She refused to pay any utilities. She's done this to previous landlords.
