Spike Bulldog

Spike Bulldog is most likely an secondary or even major character, as he has appeared in almost all renditions of Tom and Jerry and TV series. Spike is a stern but occasionally dumb British bulldog who is particularly disapproving of cats, but is a softie when it comes to mice, innocent characters and of course, his son Tyke

Why He Rocked in his old days

 * 1) Whenever he was paired with Jerry, he was Jerry's loyal and protective sidekick, this is shown in a style of a laid-back wingman when Tom annoyed Jerry in episodes like "The Bodyguard", he always help him stand up for him (whenever he is aware of the situation at the very least) and was always done satisfyingly and hilariously, sometimes both at the same time!
 * 2) With this in mind, when he is friends with both Tom and Jerry it is quite wholesome, heartwarming and fun to watch seeing how he helps or even saves his friends out in "The Truce Hurts" episode for example.
 * 3) He is very loyal and affectionate to his owners, humorously or not.
 * 4) If Tom wasn't evil or didn't attack Jerry, he didn't attack Tom in a prickly manner as well.
 * 5) Even if Tom actually treated him contemptibly or foolishly, Spike's short-tempered and ballsy demeanor was warranted.
 * 6) His barks was pretty funny.
 * 7) When Jerry saved him in one episode, he was very grateful and he helped Jerry in response.
 * 8) He will also protect his son Tyke from harm and interruption at all costs and is shown to be a very protective father. His caring nature for him was always shown in a fatherly manner.
 * 9) While Spike is usually violent with other cats or even powerless dogs that annoy or infuriate him (e.g "The Truce Hurts" being a true example for protecting Tom), he has an good reason to.
 * 10) Even when he was downplayed after the golden age of Tom & Jerry, he was still a pleasant character to be around
 * 11) "That's My Boy!"

Bad Qualities

 * 1) He has become completely out of character recently in the Tom and Jerry 2014 series, because of the fact that he was dumbed down to the point of not being his more memorable and likable counterpart.
 * 2) He can sometimes be unaware of what Jerry is suffering through when he doesn't notice that Tom was involved by how Jerry gives him sign languages of begging for help as a example.
 * 3) His loyalty (while true-blue for the most part) can be capricious with tagging along with Tom's selfish behavior (e.g "Pet Peeve" being a example of this
 * 4) Spike can sometimes shown to have a lack of common sense at times.
