It's not a silver bullet though. There's a little Corgi x Jack Russel that we see regularly since it was a puppy. The owners have been using a dog walker a couple of times a week since the beginning who takes the dogs out to forests and stuff, looks amazing in the photos. But their dog is still a dick who doesn't know how to play nicely.
Surely being total dicks (at least for the first 2 or 3 years) is just standard for jack russels?
They're great when they're older and calm down in my experience. Less so before that.
We've got a 18 month old jack russell/border terrier, he was a total dick for about 6 months but now is a really nice wee friendly dog. We have really socialised him from young though so that's helped.
No matter what I've tried though his recall is meh, wee idiot.
