The awesome thing about Inca though is that he isn't pushy with strangers. He walks along, wagging his tail like the happy boy he is, and he'll sniff people as they pass by but for the most part he keeps on walking.
As soon as someone gives him a sign of wanting to say hello though, that changes! Make kissy noises at him, talk to him in a high pitched voice, say "Hi buddy!" and invite him over and you'll get a super sweet puppy squirming his way over for some love.
Usually the way he approaches is partially crouched to the ground, tail low and wagging slowly, but as he gains confidence he's approaching people more upright and quickly. However he remains a very polite boy who will warmly take any attention and try and convince you to give him a belly rub.
