I have been a dog groomer for 35 years. Periodically we would get a customer who’s dog or cat either got deathly ill or died from Hartz Flea products. I myself, in 1974 had six cats get deathly ill from their cat flea spray. We had Dr Robinson, DVM, come to the house . He had to give them all shots. One died. When I see how many of their products in Walmart, Price Chopper and Hanaford, I just cringe. I wouldn’t buy anything of theirs.
