I think Han's killed one of his dogs when hunting...

[狐神｜Kitsugami]

during this mission where you go hunting with hans capon he starts off with 2 hounds, however after the rabbit it seems one of he hounds has went missing as he now only as one, I know I didn't kill it though witch leads me to think he did, anyways he never reacted to anything as if the player killed it either so i'm pretty sure he killed his own dog well hunting.

Does any know if his dogs respawn?

Did not happen to me, so no idea though doubt the dog will respawn.
And just curious, why the interest?

And which, not witch. English, it's a fun language... ¯\_(ツ)_/¯
