I had no idea about 11/2 years ago that I was unintentually poisoning my little Chihuahua, Boo. We had gone to the pet store and purchased the Hartz 3-pack of drops to use because it was cheaper than the other flea and tick medications. Soon after the first application, she had a seizure. I did not put two and two together because it had been several days since applying the treatment. I started doing some research on Chihuahuas and found that occasionally they had seizures. I just assumed that this was common. I didn’t think anything of it. A couple of months later we applied the Hartz again and soon after that she had another seizure. I was so scared that I called the vet and they said that they could do some blood work for about $300 but even then they may not know what caused the seizures. So I didn’t do the blood work. Again a couple months later it happened again! We stopped buying the Hartz because the smell was so strong, we still had no idea about the Hartz medicine being linked to seizures. Since we have not bought the Hartz medication, my Boo has NOT had one seizure. My husband, just the other night, was watching the local news and saw this story. He said, “I think we have figured out the mystery to her seizures”! And then he told me about the medication. I can’t believe that this is still happening to other pets after 11/2 years ago. Why are they still letting this medication hurt our animals? We must do something! I don’t know what I would do if I lost my little girl! She is very young and the seizures were the scariest thing to go through. Not knowing and worrying all the time about her, and then the guilt of now knowing that we were accidentally poisoning her is heart breaking! We must do something!
