Hi all! So our German Shepherd (8 month old male) is the sweetest, most loving boy, however, he has a lot of anxiety that I'm struggling to navigate. He definitely has separation anxiety with my dad (the person who he spends most time with) and is seemingly very startled by strangers. Whether it's the delivery driver, strangers passing by on walks, or friends coming over, he barks nonstop at them. Considering his size, people are very scared by these behaviors. He's been in obedience training for a few months now, but our trainer hasn't really discussed or worked on these behaviors. I've seen advice saying to condition him with treats (causing him to gain positive reinforcement with strangers), is this effective? Any tips? Thanks in advance ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
