Review on Soft Padded Nylon Martingale Dog Collar for Training Small Medium Large Dogs - Durable Pet Collars in Black, Orange, Blue, Green, and Pink (S, Neck Size 12" - 16") by Aaron Wilson

The piece that tightens when the dog pulls hangs and flops around when OFF leash drove my dog crazy. My Golden Retriever is the calmest dog I've ever had, and when I watched her playing (off leash) and the hanging loop flopping up and down hitting her in the face, I had to throw it away.She has a Martingale collar with a chain loop, not a fabric loop, which has never been a problem for her. I bought this because I thought it would be more comfortable.
