Why do more and more people hate dog lovers?

I don't have a dog, I haven't eaten dog meat, I don't hate or dislike dogs, and I like them a little. However, there are also some dog lovers who are very disgusted, mainly for the following reasons: uncivilized dog ownership, walking dogs without leashes and wearing masks. Don't dispose of dog excrement. There are many dogs in the family, and there is no dog license. The barking of dogs disturbed people. Don't give your dog injections on time to prevent diseases. After the dog attacked people, the breeder did not take a correct and positive attitude to compensate the injured people. Because dogs bite and scare people, it causes conflicts. The owner of the dog was rude to people and began to hit people. He also threatened that the dog is his family and his life is not as good as that of the dog.
