Some of our fabrics designed for other applications (for example: pass-through mesh for incontinent dogs) can be easily destructed. However, by choosing a stronger fabric like the 40 oz. Heavy Duty vinyl, persistent chewers will have a much more difficult time trying to shred the fabric and leave behind parts that could be swallowed. Unlike with pillow-style dog beds, the Kuranda bed is not stuffed with filling that could be harmful if exposed and swallowed by an aggressive chewer.
