My long-haired chihuahua used to follow me everywhere. Always be in the same room with me and almost always sat with me. We have been together 10 years. About a year ago she started hiding from me and quit following me and hardly ever sits with me anymore. She is all the company I have as I live alone. I took her vet and she is fine. I don't understand why she quit liking me. She barks at me when she wants something and I go give it to her. I love her so much . She won't come to me when I call her. Could I have become a bad person without knowing it? I am at my wits end. I have no clue what to do.
