Why did my havanese develop a bald spot on her shoulder that she had for 3 weeks about the size of a quarter or a little bigger

Hair loss can be caused by bacterial, parasitic or fungal infection, dietary or environmental allergies or sensitivities, immune system disorders, or a combination of the above. I'm not sure if you mean it resolved after 3 weeks or if it has been there for three weeks and is still there, but if Bella still has a bald patch I recommend making an appointment to have her seen by your veterinarian to help determine the cause of the hair loss as soon as you can. The vet will likely want to look at a sample from the area (taken by a procedure known as a skin scraping) and examined under the microscope to determine what kind(s) of infection may be present and to figure out what medication is appropriate for treatment. Good luck!
