I've had puppia for years and I am a retailer of puppia as well. I actually have a size L in black soft harness in puppia somewhere in my office. I have to look for it. But I recently got some ChokeFree harness and found that I love those better. I can tell the difference because my Naboo who is 14 lbs pulls like a husky.
When she has the Puppia on, she likes to drag with it, and she gets out of breath and gets more tired so much faster. I can see that she puts allot of strength in her neck area because the the neck part goes all the way to her shoulders area when she's pulling.
When she has the ChokeFree on, she doesn't pull as much and the chokefree stays in place. She just looks more comfortable in it than with the puppia on.
I have pictures of the differences of her wearing puppia and the chokefree, I just need to extract it from my phone.
