Real leather. Excellent quality. Perfect for handling your dog in crowded places as it offers control over the dog’s neck and head. The leather is very good quality, not rigid at all and pleasant when you grip the handle even when the dog pulls. I ordered size M for juvenile Dogo Canario female (1 year old / neck 33 cm) - used the smallest hole and it fits good because the dog is still growing so it will still fit after the dog matures.
Very nice, quality, I recommend.
