Denice is most likely the better person to ask, but I'll say, It Depends.
I have some young dogs out of my own that I am starting and two went to dog broke corriente calves after three goes on sheep, in round pen.
Two went to a dog broke flock of 50 or 60 training sheep out in fields with older dog to hold edges.
Two needed to stay in round pen to learn some basic manners on very dogged sheep.
But since I am breeding for my work I did some testing on them too before this.
I feel that a young good dog that is free moving but will come in when needed and stay off when needed is pretty easy to train. But this is breeding. It is bred in.
The feisty little devils you might need to teach to stay out and stop so they don't end up causing a ginormous wreck. but these might be the best dogs for my work in the mountains on cattle, if they also develop feel and diplomacy.
some dogs might need to be encouraged and not feel pressure from fences so they go outside and learn to keep moving and it is great they become better because they are encouraged by this with trained dog to hold edges..
as soon as a young dog will stop and go to balance i may take him/her out to do simple chores. move ewes out of corrals, little gather close in. but i will have a trained dog with me.
but here is what i have found- the thin line we walk between a dog having feel, having power, having presence, willingness to come in and grip in a good way and let go and then allow stock to move off is indeed an interesting thin line.
I have a very tough cow dog- but at distance he will revert to type, so you better remember that when working him- tho he has developed feel, learned i guess that he can create fights which make his job out here in the mts much harder.
I have another that can gather at a great distance but if one bull sneezes at him in the brush he might not be able to move him.
And I have Joe and Jake who are the backbone of my work- they were easy-and frankly not because I know anything- but Jake was a lucky nick- and Joe bred by a 30 year old ranching breeding program.
but still the tough dog i need sometimes.
so to simplify with jake and joe yes they were able to go out to the work, for tough old tick no. for my sweet guy- no for different reasons.
bud was very experienced
