Up until now there's been two ways for the dogs to get on and off the bed or couch. They can try to get on and off by themselves, which will definitely take it's toll in physical damage to the dog. Or, if you have to lift them on and off, you take the physical damage. Even if you are the one doing all the work, I suspect their little ribs, knees, and spine might start hurting too. These product are ideal for any size dog, especially those suffering from extremity injuries, arthritis, vertebral disc disease, stress, old age, etc.. By Smith-Kruger Inc. BedderBacks
