I'm trying recall games in our fenced backyard with Cleo using a 20-ft long line. Basically, we're playing ping pong --i toss food away, she goes to get it, and then I call her back and toss again in another direction. So far so good. But, I've never used a long line before, and i'm confused about how to keep both of us from getting tangled up and tripping, especially Cleo, when she's running back and forth. Even if i take up the extra length, what's left is dragging on the ground (and in my yard right now that means a lot of dragging through mud...). I can't really gather it up more because i'm having her run away and then quickly run back to me from different distances. I have the line attached to her harness, and I have been attaching it in front, like her leash, but maybe i should attach it on the back for this kind of thing? I feel like there is probably a simple answer here than i'm missing because of my inexperience. Any suggestions?
