I think he only wears it to cover his scars since it would reflect poorly on the empress he serves. Also it’s like a statement that he’s the empress’s dog/a sign of his devotion.
It would be nice if he could get healed though
still an insult
I just wanted to state that Sing is referred as a dog because that's what he is. People who are loyal (often to a fault), to one person are "dogs". This has a negative connotation in society but I doubt they're using it as such when referring to Sing. I do wish they'd take off that ugly ass muzzle tho....
