If a dog isn't 100./' on recall and stop at home. It's a big ask for it to be down at the park . If it ain't a hundy at the park then you haven't got a shit show in the bush with game around. X 10 if it's Got some hunt in it.
It's straight forward if u think about it.
If u get a dog as a pup then it's a hell of a lot easier to get it right but the down side is if u don't get it right there isn't anyone else to blame haha. I trained my first dog and did everything wrong right from the get go and had a mongrel good for nothing hound.
Which taught me a lot.
The biggest thing it taught me was 99 percent of info out there for novice dog trainers is bs.
Sure some of it might work if have a lab and u want it to shit outside shake visitors hands once in a while and drag u down to the dog park choking itself half to death till it's safe to be let off for a scream around.
But to get bonAfide info on training a gundog was and is bloody hard.
The dog I have now I picked a good breeder. Had a training plan in place before I got the damn thing. And went at the pace that we progressed at. My dog ain't perfect but Is great to hunt with. On a good day I won't have to use a whistle at all or anything verbal. On a bad day I might have to stop him a few times and redirect him.
Getting a rehomed dog like u have is always going to be harder.
I would say best bet is to start from scratch , teach it what you want it to know and don't give it the opportunity to do anything other than what u want it to.
Don't worry bout deer skins and stuff. It's got a nose it will figure all that out quick smart.
U need it close u need it attentive to you and u need it to stop on command and u need it to not run off on u. All without a rope around its neck. And in a hunting situ. Then take it hunting.
I hope it works out for u.
