The techs at PARC closely monitor the interactions between dogs in the yards to better understand their behaviors and issues. As McCarthy highlights, it's essential to distinguish whether a dog is feeling unwell due to its food or if it is responding to incidents like another dog taking its bone. This observation helps ensure the dogs' health and wellbeing are maintained.

For instance, Theresa mentions Rover, who has been experiencing stomach problems, which inadvertently affects Porkchop, as he has taken to eating Rover's vomit. This not only impacts Porkchop's appetite but could also have broader implications for his health. Understanding these dynamics is crucial for the staff to provide the best care for the dogs.
