This medium-sized dog bed is designed with a 3D structure that prevents collapse, ensures proper airflow, and allows pets to burrow comfortably. The enclosed design provides a sense of safety for your pet and eliminates the risk of suffocation. The bed features a thick, high-quality sponge base that offers strong support to protect your dog's joints. The cave-like design creates a secure environment for your pet and encourages their natural instinct to explore. Made with exclusive fabric patterns and textures, this cozy dog bed offers a unique experience. The top is equipped with thinner sponges for support, while a skid-proof pad on the bottom ensures stability. After receiving the bed, it is recommended to gently tap and leave the burrow cave bed for over 48 hours to restore its elasticity.
