If there was one thing that Wuxian hated about his life it was the fact that he had cynophobia. He remembered, honestly, when Noxeema had been in Madison and he'd hidden behind her to keep from being eaten alive by feral mutts. His husband hadn't been there at the time, but he's grateful for the other being there now.
He does not, however, expect for his husband to draw Bichen. That had been a bit overkill even if he knows that his husband is protecting him. Maybe it was a reflex thing. After all, it was what Lan Wangji had done when he, himself, had ran from Fairy that one time. Before he'd exposed who he really was.
"Safe is subjective, Lan Zhan! There is a feral mutt out there." One that he's sure will rip him apart with its teeth.
