My boykin has thrown up underwear, shat out oatmeal bath bombs made out of pantyhose for my young'ns excema, shat out an expanding foam bath toy of my sons, shat out crayons, qtips, paper towels, wife's face wash wipes. Fortunately she has passed everything she has eaten in her 4.5 years of life. Was unaware of the underwear until she threw them up. Neither of may labs have ever eaten anything like that...maybe because they live outside. Hopefully your dog will be ok.
