I wish I’d seen this site before I applied the flea-tick drops to my dog. She started going crazy and tried to bite her fur off. I searched the internet for info on Hartz products and found this site. I could not believe the stories here (and how true they must be). I also can’t believe Hartz continues to sell it’s products. I spent a couple hours hosing her down and she seems to be back to normal. Hope all is well with the other pets.
