Tbh I still don't quite get what the "issue" is. Without Pet Pal, he behaves like a normally neutral NPC, which makes sense because he actually is not a hostile-by-default enemy. He won't attack, and attacking him might not trigger a fight immediately - he just loses Attitude instead. With Pet Pal, you still have a chance to back away, but since you understand him now, you can have a proper conversation, which leads to him attacking you in the end. So why should this encounter not require Pet Pal again?
