Over the years we have had 2 different outside judges stress the need for the handler to walk on a walkup.
I could find nothing in the rulebook about this.
The judges did not want to see a "sneak" as a hunter would do while jump shooting.
One judge from Louisiana was clear that if the handler "sneaks", he would be sent back to the holding blind.
A second "sneak" by the handler would be elimination.
At our latest AKC seminar, the national rep said he had no problem with a handler "sneaking" in a walkup.
That makes sense to me since that is how most hunters who a jump shooting walk up while hunting.
Also as a judge, what if a handler is in a wheelchair, or crutches...
I do not judge, and would appreciate thoughts and what are the customs from different areas of the country.
