What was the name of Spike the bulldog's son in the cartoon "Tom and Jerry"?

"Tom and Jerry" is an American animated series of short films created in 1940 by William Hanna and Joseph Barbera. It centers on a rivalry between its two title characters, Tom, a cat, and Jerry, a mouse, and many recurring characters, based around slapstick comedy. In its original run, Hanna and Barbera produced 114 Tom and Jerry shorts for Metro-Goldwyn-Mayer from 1940 to 1958.

In his attempts to catch Jerry, Tom often has to deal with Spike (known as "Killer" and "Butch" in some shorts), an angry, vicious but easily duped bulldog who tries to attack Tom for bothering him or his son Tyke while trying to get Jerry. Originally, Spike was unnamed and mute (aside from howls and biting noises) as well as attacking indiscriminately, not caring whether it was Tom or Jerry though usually attacking Tom. In later cartoons, Spike spoke often, using a voice and expressions (performed by Billy Bletcher and later Daws Butler) modeled after comedian Jimmy Durante. Spike's coat has altered throughout the years between grey and creamy tan. The addition of Spike's son Tyke in the late 1940s led to both a slight softening of Spike's character and a short-lived spin-off theatrical series (Spike and Tyke).
