thnx for all the input. Yes I do have a "hammock" but as mentioned, it would be best if he could step into floor and then up to seat but my car does not enable that (old car did). I purposely chose this car model as it does have a "step" to get up into car. Originally it was slippery but we glued a piece of carpet along it which helped. I will try the yoga mat idea btw, perhaps it will help stabilize as the hammock and blanket on it do tend to slide when he tries to get up. He is timid and frankly I don't think he will walk up a ramp etc particularly as he is not food driven which would have been helpful. I am concerned because we use the car to travel to nice walks for him plus he is a therapy dog and I need to take him in the car to places to visit people.
