ok, i think my dog has eaten a thumbtack. but i am not sure, we have a key holder by the door that is being held in place by 2 thumbtacks, it fell and i only found one of them. i read a little on here from some searches and it seems like the thumbtack will just pass through. but i just dont know if it really wil or not. i know the only responce will be take him to a vet. i dont want to hear that. that is al i get from this forum. i want to here possibilities. thanks!!#!!
