I have a baby german shepherd dog. my father says that they are cause for disease. what i can do and what precautions i should have to take explain.?

See answer: As a physician who treats humans, I do not know of any serious medical conditions that would give cause to make that statement. A veterinarian may better answer the question. I have had many patients and some relatives who have had german shepherds and the humans have always been fine and had no medical issues related to their dogs.
