Buzz is a superfast Collie who has been working on his running A-Frame with his handlers Sam and Martin. They have been using the Doggy Stride Regulator Thing to help Buzz's foot pattern as he comes over the apex of the A-Frame and hit his contact every time at speed.
Buzz started out using the large stride regulator, but will soon be using the slim line version, the idea being is to ween him off having to rely on the regulator. Sam and Martin can then remove the regulator all together. I'll keep you posted on how he's getting on...
