I just found this website and wanted to share my story about Hartz products. A few years back, I bought a Hartz flea spray at WalMart for my rat terrier. I used it according to instructions. About 15 minutes after I sprayed my dog she tried to walk across the room and kept falling on her side and her eyes were rolling back into her head. I immediately called the emergency vet service we have and was told to dilute the spray by bathing her and if that didn’t help her then to bring her in asap. Bathing her helped and she returned to normal within minutes. I returned the spray to WalMart and told them what happened and they said that they had alot of complaints about the Hartz products.
