Thought I'd give you an update on this, we've done about 5 successful sessions so far, it's been an absolute pleasure. No problems at all really, she will sit and watch the birds on the lake without giving chase or barking at them, she loves meeting other anglers and always gives them a nice greeting when they come into the swim. Once the rods are out we do a lot of training on the bank followed by a some play time (no swimming or being noisy) she's a bit jumpy around catapults and still hasn't seen a fish on the bank yet, so will have to see how it goes lol.
All together though, taking her fishing is the best thing I've ever done, it's completely changed her behaviour. She used to have a few bad habits at home (nipping/biting, thought she was boss basically lol) but after a fishing session she is that wiped out she gets in the door, has some food and heads straight for the bed without being a little [censored] lol.
