My Dachshund rest during the day in its niche outside. With the cold winter and for it to have hot I am acquiring this igloo I placed inside the niche. Since the igloo is rigid enough I disposed over an old sleeping bag, making it a warm cocoon. I chose this article especially for its size, since my dog is not high but long. I am delighted to have been able to purchase. The quality is good for the price, lightweight and foldable for those who want to transport it. I wish foam walls are thicker to the use I have made.
