Immediately both ears come up and the pup - it's not a small beast by any means, almost as big as Noctis, but it's ill defined in a way that shows it most certainly is a puppy still. The wolf stares at Noctis, the pain already forgotten in the light of this curious new thing. There's a bit of an uncertain growl, not sure if this is a threat or not, his body crouching down as he prepares to defend himself if he has to.

Grrrr... it's still a bit of a pathetic growl, but Gladio was of a size that could do real damage if he needed to.
