That's perfect. My little puppy (3 months old) did not like at all the leaves last week and made good of goats when he felt retained (for fear). With this pen, I could finally hold the leash in hand when it was attached, allowing it to keep a certain distance at the beginning and motivating to return to me and move forward at the same time with some treats. Result, 10 days with a small training every day, he walks up to my leash like a real chef and he did the same with my companion and I could board leash 1m20 in town. Ideal for a little puppy (boston terrier) because along lègère and slight hook. Next time you use this lanyard: development of the recall.
