Review on Enhanced Safety and Training with CollarDirect Reflective Dog Collar Martingale Collars by Samuel Reppa

I was a bit worried when I bought this as a lot of people have been talking about breaking the chain. Decided I would give it a try and be able to come back if that happens. But it isn't, and I have an insanely strong French bulldog that wears this collar. If he starts pulling and that collar is stuck, he'll immediately sit down and wait to be allowed to continue. I was a little surprised it worked so well for him as we have tried all sorts of 'tension free' collars/harnesses etc. Another nice thing about this collar is that there is a small locking mechanism on the clasp to keep it from coming loose. Unpacked while walking. Anyway, my only downside would be that this lock is a bit difficult to unlock, sometimes it gets stuck, but I prefer it the other way around!
