This Sunday at 10:38 p.m. EST NBC is giving fans a sneak peak at Animal Practice. The new show officially premiering on September 26th at 8/7c stars Justin Kirk as Dr. George Coleman, a successful veterinarian who recently learned that his ex-girlfriend Dorothy Crane (JoAnna Garcia Swisher) has inherited the hospital where he works and is now his boss. George, who would rather spend time with his animal patients than with their human owners is a stark contrast to the cheerful optimist Dorothy who immediately inserts herself into hospital business.

We chatted with Justin Kirk about the show, who he thinks the funniest cast member is behind-the-scenes and what it’s like working with Crystal the Monkey who pays Dr. Rizzo on the new comedy. Check it out:
