The Guardian Gear® Vehicle Pet Ramp is great for dogs that need help getting in and out of your car. Because it is sloped, it is perfect for older dogs with back problems. It's lightweight so you can easily fold it out so your dog can walk up it and then easily fold it and place it back in your car.
Use positive reinforcement to teach your dog to use ramps or stairs. Go to the top of the ramp or stairs and call your doggie to join you. Then give him or her a treat when they get to you. This will make the experience more enjoyable for your pet and will make him more likely to use the ramp or stairs with confidence even when you are not around. If this doesn't work, then guide your doggie up the ramp or stairs with a leash. You might have to do this a few times, but soon, your doggie will be going up and down the ramp or stairs without your help.
