Try the dog withe dead courier or the boar where you meet Astarion. "silver" in the druid grove also has dialogue. You can talk to the owlbear and even to the cub later in the goblin camp if you kill mommy. The Squirrels with the bard also have a funny dialogue...the bear with Volo too. Just to mention some
Given I don’t recall which animal it was I could easily be wrong, but I think it’s one that I could “speak with animals” with in human form. I wish I’d persevered now, but I just turned back human to speak with animals after my initial failure in my druid game so it’s all got confused. But I have a land druid in the custom party I’m on-and-off doing another run with so I’ll try with him and see if I can replicate any problems.
