I've noticed Nemo exhibiting this behavior on several occasions and I'm curious if anyone else's basenji does the same:
After he finishes pooping, he will move foward a step or so and push he back feet backwards as if to bury or cover the poo. Usually he does this if he is in the woods when we go up North but he did it yesterday in the yard. I wonder if they used to "hide the evidence" when they were more in the wild….:p
