Well, it sounds like you had a very strange experience! It is possible that you contracted fleas from being a pup in the TV show. This can happen when animals are kept in too close of quarters. You may have also picked up fleas from another dog or even a wild animal. Fleas can cause a lot of discomfort and itching, and you may have been trying to scratch yourself and spread it to the other dogs. As for the bath, this may have been to get rid of the fleas and any potential infection they caused. Fortunately, after the bath, you should be feeling back to normal and the fleas should be gone.
