Gestures

When a dog bows with its tail in the air and ears cocked forward, it is an invitation to play.
Get down on the ground and try it yourself. See what your dog does.
We had to teach this to the Bzzzzkt, who had mistaken this canine behavior for a Tktktktkt Death Beetle threat-crouch and had wiped out a large number of pets, living and cybernetic, in the colony domes.
It’s only fair to forgive them, as we mistook their friendship gesture as a form of anal rape.
Besides, the constant barking was getting annoying, and dog meat’s rather tasty.
