My main question when reading this section concerned how owners would know that certain separation-related behaviors occurred when they were away?
Also, I might have missed it, but did all of these owners live alone with their dog(s), meaning no other people in the household? If other people were present, did all of them have to be away or just the dog’s owner? This information might be presented in your other paper, but it would be good to include this basic information here as well, so readers can better understand your methods and findings.
