The link that I'm about to post is in regards to dog tracking.

The reason why I've chosen to post this link is because of Anya of course!

There are three types of tracking:

Foot Step Tracking

Tracking Through Drive

Variable Street tracking

Anya is an expert at the latter two, and Matty can testify to that.
I'm trying to teach Anya to Stay (Bleib) at the moment.

She definitely gets it, she's just very distracted by Guinness. She loves him.
I'm also looking into harnesses, she wants to track as soon as the door opens.
I personally don't like the way the collar pulls against her throat.
Okay off I go to look at more harness sites.

Enjoy the link:
