Claim:
Hartz brand flea and tick products are harmful to pets.

Example:   [Collected via Facebook, May 2013]

A friend posted an "article" and a picture of a sick looking dog on Facebook. The article claims that Hartz brand flea and tick products are harmful to pets and should be removed from store shelves. (I used their products on my cat for years with no problem. I don't have pets now.) The article and photo was originally posted by a facebook group called "Hartz Products are killing our pets." Is this true? It seems to me like we would have heard about it long before now if it were. The group claims "Since 2000 there have been over 33,000 complaints made by consumers across the nation about Hartz flea products. Twenty-four different TV news stations have done reports about the effects of Hartz flea products. There has been one class action filed against Hartz, which was settled out of court."
