The scientific evidence that oils have any emotional effect on people or dogs is very weak. The placebo effect is often at work. With people, they are doing several other things to calm themselves when using aromatherapy that could account for feeling calm, like deep breathing, soothing music, relaxed setting, etc. With people claiming to use oils to calm their dogs, what is their objective evidence? Or do they just say, "My dog is calmer after exposing him to oils." The expectancy effect is at work. Plus, some oils contain volatile organic compounds that can be harmful, but, while I think the risk is low, so is the benefit. Exercising and spending time with your dog will help more than anything.
