Yikes!!! This reminds me of the time I took my dog to the vet and she was given a particularly toxic med. The technician told me to wash my hands after pilling her as the drug could give me bladder cancer!!! I told the tech that If the drug could give me cancer, I sure as heck didn't want to give it to my dog and asked for an alternative. After my hissy fit in the lobby, the vet came up and said there was an alternative but I had to dose more often. I told her that I had no problem with that.
I still cannot believe that the vet was EVEN using such a toxic drug.
