When Dr Frankenstein decides to retire from the monster-making business, he calls an international roster of monsters to a creepy convention to elect his successor. Everyone is there including Dracula, The Werewolf, The Creature, Dr Jekyll & Mr Hyde and many more. But Frankenstein's title is not all that is at stake. The famous doctor has also discovered the secret of total destruction that must not fall into the wrong hands!
If you mean "dog fighting" as in airplane fights, a bunch of airplanes attack King Kong. If you mean fights using actual dogs, not unless you count the Wolfman having a very brief fight with the main character.
The Frankenstein monster's wife often abuses him and it's played for laughs (pulling on his ear, stepping on his foot, insulting him, ect.). A character also slaps another because they think they are hysterical.
The main character says this when he thinks he's too late to rescue one of the characters. He does not carry through with this, though, and says he only said it cause he thought "no one could hear him".
A man is comically choked by an octopus from a pot of soup. One character also shoves an umbrella in another character's mouth. One character almost drowns but is saved before she is. The main character has severe allergies.
Not quite "electro-therapy", but Frankenstein's monster is brought to life with electricity, and he uses electricity on himself to help him fall asleep in one scene.
At the beginning of the film there is a huge, firey explosion involving a raven, and at the end there's a huge explosion at the end taking out an entire island.
