Yep, she started yipping, barking, pulling on the leash and trembling with excitement. I ended up finding a spot behind a huge truck, which managed to block her view of the course, which seemed to help a bit.
We took 5 turns on the course and she loved every moment. Well, until her turn ended and then I had to be fast and leash her quickly. I ended up having to pick her up to remove her from the course, she squirmed a lot and I almost dropped her a few times.
Check out her stride, she is amazing.
She looks so intense and happy.
I am so grateful this was mentioned at Just Another Dog Blog, Marley had such a great time. I have to keep my eyes open for more opportunities to do this more often.
