There are soo many things that dogs would find very confusing, if they had the capacity to analyze that way. What if they knew that all of our interpersonal interactions were governed mostly by ego, shame, and pride?

smell of us

You meant to suggest the situation when dogs wear our odour, right? Like, perhaps, they rub against us and pick up a scent to wear ?

To check for odour without wearing it themselves, it’s just “smell us”. So, I’m not sure whether it was a typo.

Well dog, at least I have nuts, ya eunuch.

If they don’t already think we’re nuts for wearing clothes.

Those idiots pee all at once and then water it down. Look at it! They’re completely insane! You could piss on so many lawns with that!
