Yep, it is open to all breeds.
It is only partially fenced.
I like the sport because my dog likes to chase stuff. And she is easily distracted outside, tends to 'range' very far, and she has a bit of an aversion to being 'caught' (she was like this from day 1). She is fine in a fenced area, and fine indoors/in new places, but I don't know.
I'm just so nervous I'm going to lose her
. I can't lose her. Maybe I should just do it and see how it goes? I don't know.
