He is 2 coming on 3.
Lately we track 4-5 days a week. (did some puppy tracks, but did not start really tracking until he was a year. We would track for a few months, then not for a few months).
Today as an example: No wind, park style shortish grass, dew. First leg about 100 paces, got to the end before he started to veer. Brought him back, made the turn nicely.... then just started left. I got frustrated, so started coming back to me.
I am pulling him back on when he gets more than a body length off the track. I have let him go farther, and he showed no real signs of coming back on his own. He did start quartering for a while, but now seems to prefer left.
Until about 2 months ago, he was tracking in a harness. When this became an issue, I swapped to the fursaver, line under a leg. Kind of freaked him out at first as he is pretty sensitive to collar corrections. That first day, I ended up snapping two lines to his collar, one under each leg, to "steady" him. Since then, just one line.
In the past he has tracked different types of vegetation, over gravel roads, through drainage ditches. No food drops. Article indication was easy-peasy. (he has been blowing off articles now- kind of hard to find them when you aren't on the track.)
Because he seemed to really be good at it, I probably pushed him too fast.
So when I started seeing issues, I backed up. But I am still seeing issues.
I track by myself, so likely have "taught" him this inadvertently. He has a SUPER nose, can find hidden objects and missing children (my daughter). But following a track is proving difficult to train.
