BEST OF ITS KIND! I have been searching for a good quality made bed that my dog can feel safe and secure in because she likes to always be under blankets. She even has a weighted blanket. SHE LOVES THIS! Material is excellent. Sherpa is soft. The orthopedic bottom is nice with no "lumps" either. Very happy with this purchase. I have a German Shorthaired Pointer and I got the XL. It's the perfect size. I would not want it any smaller. EXCELLENT DOG BED - JUST BUY IT ALREADY! I wish I would have bought it sooner. It's worth every penny.
