Getting in and out of a vehicle can become very difficult for a pet as it ages, which is why the Gen7Pets Feather-Lite Ramp is so important. It's a great way to give your pet the access it needs and it saves you the heavy lifting in and out of the back of your vehicle every time you go on a trip. The sandpaper surface tread is ideal for younger smaller dogs that do not rely on extra gripping power for going up and down the ramp. If your pet needs extra stability and assurance, the Natural-Step? Ramp with poly-grass surface tread is just what you need.
