An unpleasant trait from life in the wild is stool-eating. Barring a parasite infection in the feces, no real harm can come to your dog from this, but it is a repulsive act nonetheless.

Litterboxes are available specifically made to address this problem. They usually have an extended cover that allows your more limber kitty to enter and exit without too much difficulty. Ask your pet store about options concerning these litterboxes. Be prepared for some cats to reject these types of litterboxes for inconvenience, darkness, contained odor, or simply because they're different. Don't throw out your old box until the new box is being used regularly and has been proven to keep your dog out.

Don't reprimand your dog. Punishment in general, and over "food" specifically, may lead to other problems. Soon your dog may become possessive over the feces or transfer this possessiveness to other "treats" to him, such as a bone or his food. Try to solve the problem by keeping the cat box unavailable.

If you block off the room, make sure your cat can both enter and exit comfortably. Inability to access the litterbox, or uncertainty that an exit will be available at all times will keep your cat from using the litterbox. One thing to consider is that cats with claws on all four feet can reach many areas a dog can not, and a well-placed scratching post or cat tree and "baby gate" can give your cat its own litterbox as well as a break from the family dog whenever it feels the need.
