This whole story, though it has a comedic tone, is centered around violence. The domestic violence Nana faced, her friend's emotional violence at home, and the verbal violence Qiu faced. Mao and the dog are also victims of violence.
This manhua isn't trying to say that violence can be tolerated, but that violence is everywhere and people tend to overlook that, especially when the people are happier now. They explicitly say that there are many kinds of violence everywhere, but it usually goes ignored, like with the teacher looking down on and ignoring Nana, and Mao and the dog suffering without help.
Agreed, this comic isnt saying anyone or anything including animals should tolerate violence but instead shows what people and animals may go through without other people knowing. The author isnt condoning the violence but portraying it so people can be aware that even though it may not be seen, it still exists irl.
Read at your own accord.....
I read Ugly Little Mao's life story and I'm literally bawling, not only for Mao but especially for the dog who had mobility problems. I don't care if it was for plot, but violence against animals is UNFORGIVABLE and UNACCEPTABLE!!!! I have 2 dogs and a cat and I'm looking at them and seeing Mao and his friend. If you have a pet (or want to adopt one), you have to take responsibility for them to the bitter end (I lost my 1st dog due a heart problem we didn't know of, and had to put my 2nd to sleep because he had malignant tumors that were making him suffer).
The message the author is sending (even if it's not the intention) is that violence to animals can be tolerated (attention, this is what I'M getting, others may not agree). There should be zero tolerance for these coward and irresponsible actions. Violence, abandonment, neglect, etc. is not acceptable and should be more heavily punished. If you, for some reason, cannot take care of your pet, there are shelters, animal associations and even veterinary clinics that can help you find a new home for your pet. They depend on us and love and trust us unconditionally, they are our companions in our highs and lows, we cannot turn our backs on them and betray them like that.
When I saw the blood trickling out the dog I just couldn't handle it, I couldn't stay silent. I somehow feel kinda... betrayed or... disappointed (can't put it well into words) with the author. I will continue to read because I really liked the story, but from this point on it will not be the same (sadly).
