About a week ago, before coming across this site, I applied Hartz Flea & Tick Drops Plus+ to my black lab/german shepherd. He was fine and didn’t have a reaction to the formula. 2 days later, I woke up only to find 6 piles of diarrhea and vomit all over the house. I was narrowing the cause of this down to 2 things…(1) he is always chewing grass or digging in the backyard and maybe he ingested something in the grass or (2) I changed his food the same day I applied the Flea & Tick Drops Plus+. I wasn’t thinking it was related to the Flea & Tick Drops Plus+. The next day, I came home from work, and once again…he crapped and threw up in the living room and kitchen. After I shampoo’d the carpet, I took him for a ride in my truck so he could get some fresh air…he crapped and threw up on the blanket in the back of my SUV. His appetite over those 2 days went down the drain…he was barely eating. Talking with my mother, she told me about tv special related to Hartz products and the effects it has on animals. I quickly gave my dog a bath and used shampoo wipes to wash the product off of his spine. He was very sick that night…very weak and could barely hold his head up to look at me…looked like he was drunk. I told my gf that I would take him to the vet in the morning if the symptoms persisted. In the morning, he was perfectly fine…back to his energetic normal self and ate all of his food. It’s been 3 days since any incident and he is back to 100%. I strongly blame Hartz as a company for putting out such a toxic product and if anything happened to my dog and it was related to the product, I would track down somebody that represented that company and break their legs. Thank you.
