We have a standard flat nylon leash (3/4" wide) and it's plenty strong enough but if Riley pulls (and man can she PULL!) it really hurts our hands. Most of the time she walks nicely but when she does pull strongly it leaves me with a rope burn/bruise.
What kind of leashes have a better grip? Leather? Cotton/climbing rope?
I was thinking maybe leather since horse reins are usually pretty easy to grip.
I also keep forgetting to bring distraction treats which isn't helping the situation. I am trying to teach her to stop pulling towards stuff like other dogs and people walking across the street.
