I am having a hard time figuring out what would be the best ladder/ramp/item to assist my very large puppies into the bed of my truck as it is high off the ground and even though I use to have a previous Gt Pyr of mine put his front paws on then just picked up his rear end for him, he did have to jump down and I think it cause him (and my huge lab mix) to have earlier issues with their joints than they should have.

Do any of you have a ramp type or something else that is really stable for such a large dog to get in and out of the bed comfortably/safely?

Thank you.
