I just got a dog. she sheds a lot. i did my laundry and my panties (and clothes) are covered with her hair. will any left over hair harm my private parts?

There might be some irritation, especially if you have a sensitivity to the dog dander. But, you probably would know that by now since you would be having allergic symptoms. Congrats on your new dog!!

Agree with Dr. Ferranti. Using a static remover in the drying will likely get rid of the hair from your clothes. Having a dog will likely provide health benefit. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Wish you and your dog good health!
