I agree with a few people!

I used to take Jasper for a walk with his collar, and he pulled, and pulled and pulled! Then I got a harness, its nice and comfy, I think it's actually called an anti-pull harness.

It's a miracle worker! I love it! I'll even use it just to walk him around the yard when Im helping my mom with flowers and things because it works so good.

So, I don't think harnesses promote pulling...
