I have a goat that I have been treating for worms and cocci, the goat came from what I thought was a reputable breeder, but he is very sick. After deworming twice I had a stool sample checked and cocci and strongyles showed up still. Can my other pets get the parasites from him, as I do wear the same boots in my chicken run and throughout my yard. I'm very worried about my chickens and dog. Does anyone know? Do I have to deworm everyone!?
