I was told that it isn't hard, just need a good microscope. I foster for the humane society and want to keep a check on if my dogs are picking anything up from the fosters that go through. My anatoilian shepherd had his yearly visit and tested positive for whipworms. Last group of puppies tested positive for coccidia and now I am worried my yard will be contaminated and infect my dogs. Someone suggested just treating all new fosters as if they have it, well giving dogs a bitter tasting liquid for at least 5 days is not only a pain in the rear but can be costly. Besides I don't want to give un-needed meds. I saw lots of info and supplies for home testing goats but not dogs.
