Ok, I found them online, was going to buy, measured the dogs, and of course they are all on the end of the measurement scale. So I don't know to buy the smaller one or the larger one for their size. *sigh* Can't anything be easy around here!! LOL!
It took 15 minutes and Max stopped yanking my arm out of my shoulder finally!
Max has just turned 3 and even with a prong chocker, his desire to pull outweighed my desire to yank his neck and spine out of alignment.
Thank God I found the Walk In Sync harness. Now Max and I BOTH enjoy our walks!
I'd suggest checking to see if anyone in your area carries the harness you're interested in, so you can try it on your dog and see which size fits best. I usually try to do that with anything like coats, harnesses, backpacks because my dogs have always ended up being on the edge of sizes or between two sizes... It works out better if I can try things on them first.
I got the store owner to help me fit my dog in the sense-action harness and that also helped because she knew how to adjust it properly and everything.
