Hi all, we too experience somewhat similar challenges with Dodger, he too is 14 months. His recall is normally quite good, but sometimes he is so keen on something he forgets we're there! We shall be practising the stop - although getting Dodger to sit is somewhat of a challenge. We have restricted his free running as such whilst we concentrate on this and have joined our local gundog training club to get more specific training for him.
We went for the first time last week, I got dragged around a bit when Dodger wanted to meet everyone, and he has a lot of learning to do. They've suggested we try some other things to overcome his pulling on lead, so we're trying a slip lead. At 35kg he's a big dog when he wants to pull.
We're also working on him waiting to fetch his toys/training dummy so that every time it's thrown it's not a given that he gets it, nor is it a cue for him to go get it straight away, instead he needs to learn to wait until he is given the command to fetch it.
One other thing we're undertaking is whistle training. Ones are on order from Canine Concepts which he seems to prick his ears up to when we play the sound. We tried all the test ones online, and he seems to show a response to two of them, so we'll see what happens when they arrive.
My hope is by taking him to gundog training and learning those skills and training that it will help him develop further. He seems to be very bored with the standard training in class, so this is a very different approach.
Dodger is our first Munsterlander so we too and working hard to figure out how best to work with him for all of us.
