My two labs are like raging bulls on the lead and you basically just go along for the ride! Then this total stranger stopped me in the street one day and gave me a halti collar and since then its been brilliant. They still try to pull but it turns their head. They really are amazing. Being dragged around is so frustrating!
There are 3 or 4 sizes so if its to big they will be able to get it off so make sure it has a clip to clip it to the collar.
