[Sam, being a shapeshifter catches the scent of wolf. He tenses, turning and spotting at first what he thinks is a big, brown wolf. A blink and he sees some kid with a collar sniffing things. His brow furrows slightly, unsure what he just saw or what he's looking at. The kid definitely smells of wolf and is acting peculiar, more like what he'd expect of a curious dog.
Hige too could probably smell something different about Sam. His go to shift is a collie, so he might register as something similar!]
