Knew this guy growing up, fellow adrift miserable teenager, decades ago. Visited him at his house.

His mom had a hustle, raising, selling dogs.

House was full of dachsunds in cages, running about underfoot, barking at everything! Stinky dogs, barky dogs, so many dogs!

Anything would set them off, then they'd all bark at each other!

When buncha guys do that online, all barking at each other at once, does that activity have a name?

If not, I suggest maybe "weinerdogging".
