Wow, I bet Daddy isn't happy at all......Boomer and Cassie both like wood. Cassie used to chew the shrubs my husband tried to plant but as she got older, she left them alone...Their wood chewing is mostly pencils my kids leave out....I'm a city girl, and I don't know hardly anything about horses, but a friend of mine who has a small barn and a horse was horsesitting once, and the guest horse either chewed or rubbed or something on the wood of the stall. Her husband was not happy, either....Is there some sort of horse product out there that would prevent a horse from doing this? If there is, maybe it would work on a dog.....
