"My puppy loved this... so much so that he decided to destroy it within 2 weeks of having it. Keeping in mind that he was a 6 pound, 3 month old Westie, I admire his tenacity to attack his much bigger than him mat, but still it irks me that it was so easy for little him to destroy. He loved to sleep on it, but even more, he loved to chew it. The zipper is not heavy duty at all, he chewed the entire zipper off, pulled out the inside padding and starting tearing it apart. I would recommend this for older dogs who will only sleep on it, because I think any dog that liked to chew would easily destroy it."
