Query: Effortless walking with 110 lb. Labrador

I've been through all different types of walking collars for our Labrador and still seem to get pulled even with a prong collar (though that was the only collar, until now, that I could use to walk him). As soon as I saw this and it's glorious reviews, I knew I'd have to give it a try. I got it today, immediately fit it to my dog (X-Large size was perfect) and took him for a stroll. The entire walk, he never pulled, he stayed by my left side and I hardly held my leash--it was heavenly! I'll never go back!!
