ryle is right, that is outdated.
My vet does 2 fecal testings a year & use dewormer 3 times a year based on the findings.
Like ryle also said, vets do keep up to date on somethings, but they don't rego to vet school every year & couldnt possibly have enough time to study every new finding about everything
Just because your vet hasnt changed from rotational worming, doesnt mean a lot havent !!!!
