First I have to say thank you for this site. About a year ago I put Hartz Flea and Tick on my dog about an hour later she started licking and drooling. And we are not taking about a little bit of drool from a 60 lbs. dog. It was just a constant drool. It didnt stop until we bathed her did it finally stop her from the producing so much saliva. So I am really greatful for this site I am never using any Hartz product again on any of my animals. It’s really sad to know that I have been poisoning my dog for so many years. And even more thankful that none of them died from this horrible product.
