A devout dog lover, especially of large breeds Kulich has adopted multiple dogs from animal shelters over the years. His dog Spanky, a 95 lb pit bull terrier, was permitted to visit Kulich on the set of "Angel" during his last day of filming for the series and was welcomed warmly by series star David Boreanaz, who also has a soft spot in his heart for canines. Kulich has been known to lend his time to a rescue organization that uses behavioral psychology to rehabilitate pit bulls that have been abused. Additionally, the actor has developed a profound appreciation for architecture, and has participated in several house renovation projects. Though he has been trained to tackle woodworking and electrical tasks, his favorite aspect is house redesign, which includes such major alterations as removing walls to add more space. The work has helped to supplement his income at times and has proven to be therapeutic as well. Kulich has also taken the time to indulge his musical side by learning to play the guitar. He has written songs for the instrument, though strictly for his own amusement.
