I ordered this one and we all love it. It is so easy to put on and Sheldon is not even aware he is wearing it. Sheldon is 2.6 lbs and it fits him now and has some room to grow. I found a Puppia harness at TJMax, it was on clearance for 5 bucks, I don't like it and neither does Sheldon, it is so hard to adjust.
