Every character has exactly 1 personality behaviour and that goes through for the entirety of the anime. The comedy is the same as in episode 1, even when more characters are added to the recurring pool of characters.
Story is about a wrestler trying to open a pet shop while wearing a dog collar in his neck. The author knows about its absurdity, it is even mocked inside the anime itself. This anime is kinda a comedic parody but with very bad personality for characters and without any comedic depth.
The comedic nature also hurts its progression... nothing ever changes and there are many plot inconsistencies overall. A trivial one: who is paying for tickets in an open ring contest in the middle of the town hall.
