Tyke makes his first appearance, although he has not yet been given a name.
This is the second short in which Spike threatens to "skin [Tom] alive" (the first being Quiet Please! (1945)), and the first in which Spike literally follows through on his promise.
Though Spike and his son would be popular characters in the series, no Mrs. Spike was ever seen or even mentioned. Censorship rules of the time required marriage to take place before children were shown, even for cartoon stories. Why the censors overlooked this in 1949 is left to conjecture.
