Buying Berenyl to treat Babesia Gibsoni is like using lemon juice and tonic water for malaria. It's ridiculous to go buy that dangerous a drug to treat a dog when the gold standard of azythromycin and atovaquone is so much cheaper. Don't be lazy irresponsible owners. Go to the vet get an Idexx 2828 test. And treat appropriately. You can get azythromycin for 38.00 and atovaquone (mepron) for under 100.00 at Walmart. Only idiots experiment with Berenyl.
