I have a long and narrow field (about 600 yds x 200 yds) with some nice factors (rolling, tree clumps, brush piles).
We've been running several marking set ups here over the last month in different sections of the field - some overlapping sections. In addition, we've been running the 3 leg pattern blinds there in a part of the field that we use for marking set ups at a different time of the day.
The past couple of days it seems like my pup's marking and memory has deteriorated a little bit. Aside from handler error - is it possible that I'm over using this field and causing confusion by using the same sections for different purposes and set-ups?
