We adopted a border collie around 1.5 years old two years ago with this same behavior. He was completely paranoid and would piss everywhere if you touched him in certain places or came close too quickly. He really would turn into a shaking blob of jello around strangers, and would lose his shit around any of our Asian man friends or even around them in public, he’d void his bladder and back away barking and snarling.
Took a while for him to get comfortable and after giving him a lot of positive reinforcement and space he’s become the most extroverted love bug I’ve ever met. He regularly smashes up against me when I’m on the couch and at the most inconvenient times because he’s got the grace of an unsupported blob of ballistics gel, but what I love most about his growth over the last two years is that now he’ll even try to put his nose under unsuspecting pedestrian’s hands on walks! Even if they’re Asian men!
He only pees now when he knows he’s in trouble
