Spike and Tyke

Spike and Tyke

 

Spike and his son Tyke

In his attempts to catch Jerry, Tom often has to deal with Spike (known as "Killer" and "Butch" in some episodes), an angry, vicious but extremely dumb guard bulldog who tries to attack Tom for bothering 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).
Most cartoons with Spike in it have a system; usually Spike is trying to accomplish something (such as building a dog house or sleeping) when Tom and Jerry's antics stop him from doing it. Spike then (presumably due to prejudice) singles out Tom as the culprit and threatens him that if it ever happens again, he will do "something horrible" to him (effectively forcing Tom to take the blame) while Jerry overhears; afterwards Jerry usually does anything he can to interrupt whatever Spike is doing while Tom barely manages to stop him (usually getting injured in the process). Usually Jerry does eventually wreck whatever Spike is doing in spectacular fashion and leaving Tom to take the blame, forcing him to flee from Spike and inevitably lose (usually due to the fact that Tom is usually framed by Jerry and that Spike just doesn't like Tom). Off-screen, Spike does something to Tom and finally Tom is generally shown injured or in a bad situation while Jerry smugly cuddles up to Spike unscathed. At least once however, Tom does something that benefits Spike, who promises not to interfere ever again; causing Jerry to frantically leave the house and run into the distance (in Hic-cup Pup). Spike is well known for his famous "Listen pussycat!" catchphrase when he threatens Tom, his other famous catchphrase is "That's my boy!" normally said when he supports or congratulates his son.
Tyke is described as a cute, sweet looking, happy and a lovable puppy. He is Spike's son, but unlike Spike, Tyke does not speak and only communicates (mostly towards his father) by barking, yapping, wagging his tail, whimpering and growling. Tyke's father Spike would always go out of his way to care and comfort his son and make sure that he is safe from Tom. Tyke loves his father and Spike loves his son and they get along like friends, although most of time they would be taking a nap or Spike would teach Tyke the main facts of life of being a dog. Like Spike, Tyke's appearance has altered throughout the years, from grey (with white paws) to creamy tan. When Tom and Jerry Kids first aired, this was the first time that viewers were able to hear Tyke speak.
