I purchased these taurine capsules for my dog who is in the midst of fighting off Nutritionally Mediated Dilated Cardiomyopathy from his Grain Free Dog Food. Sadly he is the first Cavalier King Charles to have tested positive for the condition. Every day is a battle. I wish that NOWROOZI would make a taurine capsule in 250mg. For the moment, once a week, I have to divide each of these capsules in half, carefully measuring the dosage, to add to his Pimobendan cardiac medicine. The moral of the story is, “don't feed your dogs grain free dog food.” Grain free dog food you're killing our dogs
