My ageing springer spaniel was finding the jump into the car increasingly difficult and obviously painful. I've seen some steps and ramps for sale for around £120-£180, so it was good to find a much cheaper solution! He happily uses these steps and waits for me to get them out of the boot before he even tries to get into the car. I "trained" him to use the steps using food rewards. He got a reward for approaching the step, and then another for putting a paw on the steps, and then another one for stepping up. He soon got the hang of it. The only downside is that the steps do not fold down, so they take up a bit of boot space. You could dis-assemble/re-assemble them of course, but that would take you a couple of minutes - you wouldn't want to have to do it every trip. The bulkiness only causes a problem when we go on holiday, and the steps compete for space with other luggage. Apart from that, they are light enough for me to lift with one hand, and sturdy enough for him to feel confident about using them. Overall, I am really pleased with my purchase.
