Hi Carolyn,
Eating wood should be discouraged due to the splinters. My Lottie was terrible for picking up and eating anything and everything but luckily has grown out of this habit on the whole :wink:
Lottie could always be tempted away with a treat. I always take treats that she loves and that she only gets when out for a walk. Have you tried cheese or liver cake? Most dogs will do anything for these treats.
As soon as you release Bailey from his lead I suggest giving him a treat to let him know what you have in your pocket so that he knows what's in store when you call him :wink: The liver cake is usually a winner.
