the habit is a survival strategy as they are recycling, and of course if the dogs poo she eats have poorly digested food then it has plenty of nutritional value left.
I have had this problem with my foundation bitch when she was on a diet following a litter, so had two reasons to do it hunger and of course she had diligently disposed of her pups poo unless I got there first.
I did manage to break her of this my diligent cleaning up, and of course when she came off her diet she was less hungry.
Every now and then she would do it if I had a dog staying that was on different food from everyone else, or a pup on puppy food.
