I have a 11 month old female Lab. She eats everything in the yard. Twigs, rocks, dirt clogs and mulch to list a few. She throws up her food and surprise treats. I have tried the command drop it with other objects and it works but not with the foreign objects. For her safety, I am thinking of using an E training collar or muzzle. I don't want to take away the joy of her catching the ball but a muzzle my be the way. At least till she kicks this bad habit. Any ideas or resolutions you all have been successful with. Thanks from the Magic man
