To select the right size orthopedic bed for your dog, consider their weight and size. Ensure the bed allows your dog to stretch out fully for comfort. Consult your veterinarian for guidance on choosing the appropriate bed size based on your dog's specific needs. It's crucial to provide ample space for your dog to lie down comfortably, preventing any joints from hanging off the edge. Opting for a bed that accommodates your dog's full length allows for proper support and ensures they can rest comfortably without any discomfort.
