"So Tux has been doing really, really well with responding to my commands. He’s doing more talking with his barking with less frantic or nervous barking. Could it be possible that the disc is radiating on to Sherlock (companion dog) as well? The reason I mention that is that they both have calmed down on their barking at squirrels and passers-by when I am in the house. They definitely sound the alarm but its much more short-lived and less frantic."
