If you share your home and live with an animal, especially a filthy dog that pukes,shits,pisses all over the place and eats anything you will pick up parasites. The dog will be ok because their immune systems have not been ruined like ours, and that's why they can eat disgusting things we can't. Get free of the animals even if it means getting rid of the idiot that owns the damn things. Your health depends on it.
