My husband had gave our Dog a bath with Hartz my dog ended up vomiting in the living room running to the bedroom and vomiting multiple times. I had my son take her out and told him to give her a bowl of water he proceeded to take her the bowl of water found her lying there panting and unresponsive, he came and told me I ran outside and she did the same thing was panting and not responding to her name no movement very lethargic! The vet recommended Frontline or Vectra and advised me to not use Hartz on my dog I can see why now after all the reviews on Hartz products they should have been banned long time ago! And after seeing my sweet happy healthy dog lying there suffering. Shame on you Hartz!
