After many observations, my dog seems to show no significant signals before she wants to pee/poop. She may be investigating the place before she goes, but it's no different from her everyday searching. she never turns around and poop wherever she wants. Recently, I've taken care of another dog for my friends. Every time he wants it, he always turns around and goes to a grassland. I asked my friend how this happens, he said he doesn't know. He's gifted to act like this. My dog is 1 year old. Is it possible to make a change on this?
