So many of those poses and positions are the same things I see Paco do. I'm also no expert, and Paco's my first dog that's mine-all-mine for me to watch all the time, but I feel like Tag's face is very Basenji-like…and if he yodels as well...
if he doesn't have Basenji in him, I'd at least say you could describe him to others as a Basenji-like dog.
