Quote FEWill: (under causes)

By simply adding methylcellulose in supplement or form as well as bran or pumpkin supplements or treats, it will almost immediately remedy the constipation. It will also help if your dog eats a lot of bones or for that matter sticks or sand, as they can also form hard masses that will cause constipation. And as all owners know, from time to time, your dog may eat almost anything that gets in their path.

This doesnt seem to be worded right. It surely wont help if they eat bones sticks or sand!
