Wow! I have ordered XLARGE dog beds before but all were no match for my Anatolian Shepard Dog (she’s basically a pony). This case in the mail and I was worried when I saw the box size but when it came out it was more than enough room for her. It’s like a big giant pillow. She’s actually sleeping on it half of the time too. She prefers the hardwood floor over her old posturepedic fancy one. Plus, this one is very affordable.
