Dog Boat Boarding Ladder Needed any ideas

Hi I have an Irish Setter and we have just changed out boat from an easy to board motor cruiser to a Trawler Motor Cruiser which has a boarding platform at the back with about a 3ft (wall) is what I would descrobe it as with two small steps to board, this is okay for people but my Irish Setter would never manager does anyone know where I could get fold dog steps or a telescopic ramp the dog steps would need to be fairly large or she would be terrified and I also think the steps would be better for her. Please help if you can I just keep coming up with American Sires.

Thanks but a bit too heavy duty the boat is onby 36ft long!

Well I am disappointed....
Wouldn`t a folding ramp they use for getting old dogs into cars work?
