He doesn't tell her about Boxer's... Reservations when it comes to other canines, partially to avoid giving himself away if she hasn't noticed what he is yet, but also just to watch how Boxer reacts without anyone feeling stressed or apprehensive.

Boxer's a little wary, looking up at Eames first before he steps forward to sniff at Laura's hand, relaxed by Eames' presence and hand on his side; he's not met many werewolves and the smell of her has definitely made him curious, now with permission to get closer he starts scenting at her hand and then drops his head to her feet as if to confirm it's definitely her, and after another look up at Eames he surmises that this is a new friend and presses his face into the palm of her hand.
