This is the third and final of three appearances Frank Ferguson makes in the series, each time playing the role of the local veterinarian Doc Peter Wilson. In the next season and all the way through season 11, the role of the local veterinarian, albeit Doc Frank Weaver, is played by Arthur Space.
This is the second of three appearances Trevor Bardette makes as Joe King. The other two occasions in which he appears playing that character occur in The Gun (1954) and The Dog Show (1955). In seasons five and six, he reappears, but playing the role of Sam Burke for three different episodes.
