Neither first attempt was perfect, but they got it in the end. The clips show their success.
With Finn I had first set up a line of jumps along the edge of the concrete. Then putting the tunnel (okay a barrel) in the middle I started to bend the line out in an arc over a period of several days.
This was quite a big jump from the previous curve, so even though he didn't get it first time - without being brought back to do the jump he missed - I was delighted that after only a couple of attempts Finn was able to achieve this:
Oh and this is just a photo from a walk on Christmas Day. That's Pixie (Finn's sister) in the foreground and Finn behind her.
Hoping for some better weather soon, but in the mean time Finn gets about 5-10 mins practice most days after his walk with the terriers.
