Negative Positive
Title: Not suitable for super active dogs, like Whippets.
Review: My 33 lbs. Whippet is very active, especially at coursing and racing events. After some slight pulling, which lunge buster holds ok, he pulled again with all his weight, and lunge buster fails. The inner elastic rope thorn apart from metal ring to which it was connected. Since outer coating is solid, it was required to make the opening in it, to pull elastic rope and connect it again to ring (pliers needed).So if you own a dog with great pull ability, this is not your product. Or prepare for some DIY-stuff
