Query: NOT THE BEST HARNESS

I bought this for my 80 lbs. boxwer. He loves to go for walks, but pulls a lot and I cannot walk him. I bought this harness because I heard good things about it, but here are the main flaws I found:- difficult to find the right fit/ difficult to adjust- the leash connects at the chest area, not the back ( which is odd)- one of the buckles hits right under the armpit, causing injury** after using it the first time, I noticed my dog was bleeding from under his right arm! It turns out the buckle kept rubbing on his skin, causing it to bleed. I resolved the problem by adding some padding around that part of the harness so it wouldn't hurt my dog. It seems to have worked.BOTTOM LINE: not the best product, probably not suited for all dogs.
