Gentle Leader Dog Pulling Prevention Device - Color: Beige - Size: L (for large dogs) The Gentle Leader is, in my opinion, a very effective device for preventing pulling, but it seems that it works for some dogs and not for others (those who dislike it). Some dogs may initially dislike it but gradually get used to it, while others may dislike it so much that walks become impossible. Therefore, people may hesitate to buy it, thinking, "It might be a waste of money..." This item was used during dog training lessons. Various dogs tried it for a short period, and some decided to buy it, while others gave up. It's still usable, but the metal and plastic parts are scratched. I'm offering it at a low price for those who want to try it but can't decide to buy it. Even young and energetic dogs may gradually calm down and stop pulling. Why not give it a try for enjoyable walks? #LargeDog #Pulling #PullingPrevention #Training #Harness
