I know that there is a no pull harness out there....I saw it in a catalog...I don't know if it works though...I may need to get one myself....my little darling is fast catching up to the weight of your guy at only 8 months old....and when he goes to run after something....like a BEAR this am....it is getting very very hard for me to stop him! I'm looking forward to hearing if there is one out there that works!~
