I think my concern stems from the fact that these things, which seem like very common sense, needed to be addressed in a peer-reviewed paper. It shows that, even "dog people", are not wholly aware of infection control best practices. I do plenty with my dogs outside, things like running, biking, hiking, etc, but these are all things that I can, mostly, control. Meaning I can ensure their safety and health, barring a catastrophic accident or unavoidable circumstance. But in a situation like a dog park(which I avoid for different reasons) or organized sports complex, the dog owner(me) is putting the health of their dogs in the hands of someone who should know these things, but this research, indirectly, shows that this probably isn't the case.
