I used the Hartz products several times, and each time with horrible results. Thank God I have never had a pet die. Each time I used the product on my dogs, they would become very lethargic and always seemed to end up scratching so much more after applying the product than they ever did before. I honestly kept thinking it was my imagination about them being so lethargic, and I even asked a friend about it and he said I shouldn’t worry, the scratching was because the shampoo and drops were causing the fleas/ticks to move more as they were getting away from the chemicals. To make a long story short, I decided to do a little research today on the Hartz product to see how it compared to other products. I came across this site and needless to say I am flabbergasted and sick. I absolutely had no idea I was poisoning my dogs. I’m not sure what I can do, but if there is anything I can do to help in this class action suit to keep Hartz and other companies from killing our pets and making them sick, please let me know.
