What episodes of 'Dog The Bounty Hunter' has Justin Bihag been in?

I know he was in most on season one, then got fired, but ive also heard rumors that Dog brought him back recently but am not sure cause I haven't kept up with the show after season two. My cousin is a big fan of his and I wanna make her a dvd with all the Justin episodes on it for her bday thats coming up. So, please let me know ALL the episodes he has been in on the show up until current. I tried to check IMDB and did some research but come not find out ALL episodes he was in.
