I have a Golden Retriever and this jump was the perfect size for him, he is new to agility so I have set the cross bar low at the moment but it has the flexibility to increase the height as he gets better at jumping over it. I purposely picked this jump as you have the option to fix or balance the cross pole. Having done agility with a previous dog it was very important that the cross pole can fall rather than bashing into my dogs legs if he doesn't jump high enough. The ability to balance the cross pole makes it extremely safe for dogs new to agility. Comes in a nice bag to keep it all together when not in use and the quality looks as good as other agility items I have bought. Very easy to put together no need for any instructions.
