At some point along the hunter’s path/taming the beast questline the quest giver did not give me the next quest in the chain and that quest was not available. I’m not exactly sure which part of the chain this occurred at because I moved on assuming I had everything done when there was no follow-up quest, but I eventually realized that I could not train my pet. At that point I checked my quest log (nothing) and then I went back to the potential quest givers (Jacoste and Dazalar in my case) and neither had any available quests. After a long back and forth with the GM’s they agreed that this is a bug. It’s a pretty serious bug, because leveling a hunter without being able to train your pet is a serious handicap that will just get worse at later levels.
