I had a couple dogs of the same mix, these dogs need a job, they are very active and always getting into something. They were outside farm dogs.
Keeping one inside would be difficult, IMO . The key would be like we did with our GSD who was an inside dog. All 117lbs of him
We found by getting him lots of toys, he kept his attention on destroying the toys and not the furniture. Even as a pup he was the perfect angel, we attribute that to having at least 20 Toys in the house to keep him occupied, plus he always got at least 2 hours of exercise as a minimum even on rainy days.
The Blue Heeler,Aussie mix are herding dogs, they have a great natural instinct for this and a Lot of energy.
Lots and lots of Toys and Lots of long walks would help a great deal if you are trying to make one an inside dog.
