Gave my dog 3 wafers (she was 83#) of GNC calming tablets. In an hour she dropped dead on the floor.
She had been running and playing in the yard before that. She had hypothyroidism most of her life and was well treated with Soloxine tablets. I called GNC Safety and Customer Service and they told me "They don't test their products against any medications for adverse reactions or underlying conditions such as hypothyroidism. Why then is there no CAUTION or WARNING label on this product at least telling customers that they don't test so they can call their vets.
Natural? I would re-label "Dog-Killing Tablets." If their attitude was at all sympathetic (they won't even refund my money), I could at least have a shot at healing instead of crying.
Monetary Loss: $2000.
