Unfortunately, this pet-owner energy mismatch extends to those who live in all types of environments. People will often seek a companion putting plenty of research into their looks, size, and how much they shed - without paying mind to the breed's temperament. I work with high-drive waterfowl retrievers that have seemingly endless energy and they can really start to act up without proper frequent exercise. They require multiple 20+ minute sessions of training/running per day that would be equivalent to many miles of running each session.
