Long anecdote to imply that most divorces are like that. But there are also stories of women divorcing because the husband cheated or because he beats her. And then the ones of women who have a full time job and take care of the children and the house without any help from their husbands. Sometimes the husband is even unemployed and not bothering looking for a job. Or consume substances. Point is, there are plenty of reasons to ask for a divorce but if you look at the data, apparently, not sharing house chores (which means that the wive ends exausted) is the more common.
And yes, you can kick your dog and the dog would still love you. And you can completely control the dog. That doesn't mean it is right and it is even worse if you do that to a woman.
I encourage you to have a dog, but I also want to point out that comparing women with dogs is disrespectful and that is other reason for divorce. Turn it around, would you want to be in a relationship with someone who expects you to be like a dog? If the answer is no, then you might have a glipse about why some women ask for divorce.
