Dog beds are specially designed resting spots that provide comfort, support, and insulation for dogs. They come in various styles, such as orthopedic beds for joint relief, bolster beds for dogs that prefer head support, and flat mats for use in crates or during travel. Made from materials like memory foam, polyester fill, or cooling gel, dog beds help promote better sleep, reduce pressure on joints, and keep pets off cold or hard floors. They're available in different sizes to suit breeds from small to large.
