I think that’s interesting, I think there may have been a bit of over reaching as to the capacity of a dog to hold magical powers to ensure smooth running of a trial though. There are many people who love dogs however are also also people who are afraid of dogs, who are allergic to dogs, who are easily distracted or find the need to try to be aware of where a dog is may be hinder them from performing their role in court as well. There’s all kinds of people involved in court proceedings, it’s complicated and demanding and high pressured and they all need to be considered as well.
Also I though the author saying that there are only two types of people dog lovers and psychopaths meant there was a bit of personal bias there! 😂
