I am also very over protective....I am cautious about the chemicals I use on /in my babies to prevent fleas,worms and heartworms. I use dzfferent things, individualized to each dog. The thing ALL my dogs get, is milk thistle....it helps the liver clear their system from toxins. I feel better giving it to them...and I have done so for years. These babies are exposed to sooo many toxins....some we deliberately give to them for preventatives, some they get into just walking around in public or the yard, things we do not know about. Rather safe than sorry.......... |
