It took 2 days to change our furnace and install an AC unit. Most of the work was in the garage and on the side yard, and Skye did pretty well! She hanged out with us in the living room or outside in the yard.
She growled and barked at the crawl space vents when they went under the house. But I would probably have done the same in her paws!
Afterwards, she thoroughly inspected the work :)
