That protest made Corvo frown momentarily until he remembered 'dog' then he chuckled. "No, no collars or leashes or tags. The only collars human wear are the ones on their shirts and they're nothing like what dogs wear." He was aware that wasn't exactly true but he felt that now was not the time or the place to get caught up in a discussion of human sexuality and fetishes.
"Let's go to my apartment. I've got everything we'll need there as well as food," he said, hoping Ben would forgive him for the smell. But he wasn't sure Tramp would have the basics all things considered and they were of a similar height, though Tramp was much leaner, so his clothes would fit well enough though they'd be a little baggy.
He gestured for Tramp to walk alongside him. "Firstly... washing. Most humans have a shower or a bath with soap every day though you could probably push that out to every second or third day as long as you haven't gotten too dirty or sweaty." He smiled wryly. "Stale human sweat and just plain dirty human is a very distinctive and unpleasant smell. Believe me, I know. I went six months without washing once and I smelled ripe by the time I got out. Our noses might not be as good as a dog's nose but this is one smell that will register very readily. Besides, smelling good means people will like you." He paused and grinned. "And maybe even invite you over for a meal or two."
