There was a small problem when some other dogs moved in next door a couple years later, and she decided they were her pack instead of us, but it was just a matter of recognising the problem and re-establishing dominance.
Mostly just by spending more time with her and limiting her time with the other dogs.
Boonie dogs tend to value having a family; they aren't loners.
And they're usually house-trained, or very near it, which is convenient.
Once you clear up whatever infestations they picked up on the street, their baseline health is sturdier than many pure breeds, partly because they have more diverse genetics and partly because the weak ones probably already died (aw).
Some boonie dogs refuse to become indoor dogs, which is understandable, but that isn't symptomatic of any underlying personality problem.
