I see all the controversy about the CynoSports games using 22" spacing, but while I understand the concerns of those voicing their concern, CynoSports hasn't ever used 24" spacing in the past so claiming that USDAA is responsible for causing them all this trouble for their dogs is a bit off.
Just as last year when the pole spacing was 22" so it is planned for this year... shouldnt come as a surprise to anyone.
Granted very large dogs need space, but for many shelties, they are faster with the 22" spacing since 24" requires the smaller dogs to reach further for every pole.
I have no argument against the assertion that 24" is safer, well so is 26" and 28" for that matter, but USDAA rules clearly states 22" with up to 2" variance allowed. A bit of a storm in a teacup, really, considering that other equipment might not be identical to what the dogs have bee accustomed to, such as surfaces, pivot point, dw bounce or the width of the jumps. The response on those has always been "it's a training issue".
I train my dogs on 21", 22", & 24". I stopped doing 18" a few years back.
USDAA has come under several rounds of calls for changing this spec or that spec. to meet the perceived needs of individuals dogs & if all such things were acted upon by all venues there would be little to differentiate them & we'd not be competitive in international venues.
