TB is Serious in Dogs
Please Read Dr. Mark's Advice
The approach to preventing transmission would be the same precautions that we take to prevent transmission in humans, namely no spitting, coughing, or sneezing around your dog and good environmental hygiene. Also, follow all of the same precautions that his doctor recommended for prevention in humans.
Once the infectious period has ended with TB, we do not have to worry about transmission. If your father's MD is comfortable with him being around other people, chances are he is okay to be around your dog.
Skin testing is possible, but I would recommend that you go to a specialty hospital or veterinary college (if there is one in your area) to get this done. If the result is negative, have the test repeated in 6 weeks to be sure. If he should show positive, unfortunately euthanasia is what is typically recommended because of a poor response to treatment and the public health risk. Thanks for the question!
