Followed by UKA many other associations announced to stop using the chute.
UKI suspends the use until a safer design for the chute is released and tested. They will then re-evaluate the possible reinstatement of this obstacle, although as before, it would not be a required obstacle in any class.
WAO states they will not be using the current design at the 2017 event. If a new design comes in and is approved by the WAO, they will decide on its use considering time factors for individual countries to train and become accustomed.
AKC will suspend the use of the collapsed tunnel in all courses until the concerns can be resolved
USDAA announces the collapsible tunnel has been removed from the list of approved obstacles for USDAA-licensed and produced events.
USDAA undertook a review of the obstacle and sought out reports, videos, and photos that might shed light on problem. They determined that specifications needed to be revisited to address the more varied surfaces used for events today.
Over the past few months, they have had discussions with equipment manufacturers and others on the identified variables, ranging from the different surfaces upon which events were being held and whether a tunnel was staked, weighted or otherwise secured, to the weight, length, construction (hemming), and other factors related to the obstacle itself.
After studying the variety of environmental and operational factors, it was determined that increased incidents of entanglements were the result of a broad set of attributes. More specifically, characteristics of the fabric in a variety of environmental situations, combined with the speed and impact with the chute material in what has become a fast-paced event were the cause, and not chute length alone. Receipt of a third-party report submitted to USDAA late last Friday, addressing physiological issues for dogs surrounding an entanglement or uncontrollable exit from the chute provided additional support to their findings, which facilitated their current ruling.
This makes it very difficult for other associations to defend to keep on allowing the collapsible tunnel and even more difficult for their judges to use it in their courses as they might be held liable for using a non mandatory obstacle that has been proven to be a dangerous.
