I think it's not to badl. Yes, this is a isekai manga with a common premise. The main character was transferred into another world and have a super power and he was reincarnated as a wolf or fenrir, but for a manga which is written to be read while relaxing and and have a story that is not too intense or serious, it's not to bad. At first we are shown the main character who dies and then meets the goddess who will reincarnate him, just like the isekai story in general. However, what is quite unique is that the main character asks to be reincarnated as thepet dog of a rich woman. although there are indeed some isekai stories where the main character is not reincarnated as a human but another creature such as a slime, a goblin, or even a sword.

To be honest, this manga is not as exciting as "Tensei Shitara Slime Datta Ken" or maybe "Tensei Shitara Ken Deshita" which has a story that is more towards adventure and action. However, I don't think that's the focus of their story. they present a simple story with comedy elements that are more highlighted. You don't have to think too complicated or too long, you don't need to be afraid of the arrival of evil characters who will terrorize you so that sometimes it's hard to sleep.

While reading this manga all you need is to sit down, relax, and prepare some snacks if you want.
