This CozyUp ramp is great for small dogs and older pets. I have a 25 pound dog who is 12 years old, and loves this. Took a little persuasion with treats to get him up the ramp a few times but now does it on his own. He was getting too old to jump and has arthritis. He seems to be moving better after using this, less soreness. The only thing is I wish it would fold. It would be more convenient to be able to  fold the ramp and put it to the side while not in use.
