We got to start backchaining sequences of obstacles tonight. SO MUCH FUN!!!!
But after we had worked our way up to starting a tunnel--jump--A-frame sequence, Roscoe saw a critter. And that was it for him. He entered another world.

So I took him for a jog around the field and we did puppy push-ups in a corner to get his focus back on me. When it was my turn, he sailed through the sequence like a champ!
But then we had to turn around a do a sequence with a curved tunnel going TOWARD the critter. He was having none of this going through the tunnel nonsense. So the instructor stood on one side and I was on the other side to keep him from breaking off and running off one side or the other. So what did my critter-obsessed hound do? He leaped ON TOP of the tunnel and ran it that way!
And we got more "Bella is part border collie" proof. There were sheep in the field next to the play area, and she went NUTS when she saw them. She ran the fence trying to get at them and several times tried to either climb the (very flimsy) wire fence or go through it (her head through one square of the fence and each leg through another two squares). If I took her collar and ran her down to the other side of the field, she flew back to the sheep the moment I let go.
Anyway, lots of fun was had tonight
