Our puppy is now 6 months old and still feels the need to eat her own poo. She is crated when we are out, which is never more than 3 hours. She asks to go out and goes for a wee in the garden but will come back in then nip upstairs and do a poo when she thinks no one is looking. She quite often poops in the garden but still attempts to eat it unless we shoo her off. She is not remotely interested in the poo of our other dog or any other animal(we live in a rural area), nor is she interested in her own once it is cold. We have increased her food on the advice of the vet who suggested she is hungry but no improvement.
Any constructive advice would be very much appreciated. Thank you.
