I’ve never used any Hartz product on my dog, a six-year-old, medium-sized mixed breed, before. She has had fleas in the past, once we used Frontline. I saw Hartz in Waldbaums and, being cheaper, I figured it was worth a try. I wish I had done my research first. After applying the drops exactly as directed, she began scratching and biting uncontrollably, particularly in one spot on her left rear. She was losing hair behind hear ears, near her shoulders, and under her collar. Within a few days, she managed to wear a quarter-sized hole in the spot that she was biting. It was pink and inflamed and kept getting bigger, so I took her to the vet. The doctor said she probably had a flea bite, had scratched it, and it was infected. But he couldn’t explain her hair loss. We got antibiotics and an inflammatory shot. The kicker is, as I was paying my bill, the receptionist asked if I wanted to purchase Frontline. I told her, no thanks, we did a flea treatment recently using Hartz. She and the other woman at the desk were like, “Oh my god, no, that stuff’s no good.” They didn’t explain further, but that made it all click – of course! This behavior had only started after the treatment, and she’s never done anything like this before. Now I’m stuck with $233 vet bill and a very unhappy dog. Luckily, the infection appears to be on the mend thanks to the antibiotics.
Very glad to have found this site so I know that I’m not alone. I’d love to be part of some sort of action or cause to stop this company from selling such obviously harmful products!
