Ok, this pet ramp I was unsure of at first.  I really think they they would do better if they would put a shaggier carpet down for the animals to go up.  I don't think it would be as easy to slide on it and totally get the comments of other customers that their dogs were afraid and wouldn't go up it.  What I ended up doing was taking a twisty treat of theirs a tap it on the carpet ramp and call their name and once they put their paws on the ramp I started tapping it and at the same time bringing my hand up the ramp without stopping and before they knew it they had climbed the ramp!! I gave them a big hugs and clapping and whoop, whoop. And the next few times got better and better. Now, it's they've always had the ramp. We have 2 chihuahuas, one half cocker spaniel / poodle.
