Pig stomachs are large, flat chews. Perfect as a tasty treat.
In appearance they are very flat but these really does change the habit of how your dog chews making it a bit more of a challenge. The large flat surface area on these are great for dental hygiene as due to the shape your dog will chew in a different way reaching different areas of the teeth and gums.
The texture of these is also very easily cut to make smaller chews if you wish.
