Well Hazel, turns out that my nephew's dog was in a day care for two weeks while they were on holidays. Bingo! I told them they should be calling the daycare to let them know, not in an argumentative way, just to let them know that like lice in kids they may have rampant mites there. I also ran into my vet (well the girls vet actually
) at the store today and asked him if he'd ever heard of getting mites from food and he said no definitely not. I told my nephew he needs to get a new vet theirs is an idiot.
