Tall Tails built the Cuddle Donut around the way puppies and kittens sleep against their mother — pressed into something soft with a raised edge to tuck against. The sides are bolstered the whole way round and the bed is deliberately overstuffed, so a dog that burrows and curls has something to push into. The shell is their Real Feel microfiber, which is the soft side of the fabric rather than the hard-wearing side. This is the X-Small, 17" x 17" x 6", suited to pets up to about 10 lbs. Machine wash cold on gentle and tumble dry low — this size goes straight into the washer, cover and all.
