After some advice. Willow eats my other 2 dogs poo, not her own, nor any other dogs that we come across whilst out on walks. She started doing it when she was about 3 months old, after my older lab had a bout of gastroenteritis. I'm assuming it's become a behavioural problem, but need advice on how to stop it. I try and stop her if I'm out in the garden with them and out on walks it's more controllable when lead walking, any suggestions? Thanks in advance
