Love this bed! Even more importantly, my little fur baby princess loves it. She is a 5 pound Chihuahua and measures 14" long from the base of her neck to right in front of her tail. The bed is a size medium. I probably should have ordered the small, but she loves it, so we're gonna keep it. I'd highly recommend getting this one.
My 3 Yorkies collectively weigh 16 pounds they fit perfectly and simply love love LOVE this bed. It comes vac sealed took 20 minutes to fluff up, took my girls 20 seconds to hop in and pretend I no longer exist.
SERIOUSLY though they love the bed, I love this purchase!
My miniature dachshund just loves this bed. Soon as I took it out of the box she didn't even give me time to fluff it and set it out for her. She jumped right in it and start being silly then laid down in it. So for my pup, it was love at first sight. This bed is so soft in many ways. My pup always looks so comfortable in it. Heck, I want one for me. Lol
I bought the small size and it's just right.
