I ran into my neighbor's dog being walked by a pet sitter today. Decided to ask about the services they offer, and mentioned the fact that I was looking for a sitter for when I'm out of town.
Turns out, he has a Basenji, R/W male.
I was so relieved to have found someone who does this for a living, and also has a Basenji at home. I think I may setup a time to see how well his B gets along with mine. If they do OK around each other, this will really be convenient for future trips. I'd be 100% worry-free leaving my B with a fellow B owner, especially someone setup for watching other people's dogs.
Here's the link to the company:
