Christmas morning started like any other but quickly took a very scary turn. I put my beautiful 2 1/2 year old lab (Abby) up while I dressed which took me about 45 minutes. When I went to get Abby she was suffering terrible twitching, dilated eyes and was slobbering profusely. I panicked because I had never seen anything like this but had enough composure to immediately begin making calls to see what to do. I called a local pet groomer and explained Abby’s symptoms to her and shared that my husband had treated her for fleas the night before. The groomer asked if my husband had by any chance used Hartz flea killer and upon speaking with him found he had. Her response was that this product was nothing but poison and Abby’s symptoms were typical of some pets that had been treated with this product (Hartz Ultra Guard). She suggested I get her to the vet immediately. Upon arriving at the vet’s office and after explaining the previous nite’s flea treatment the vet said she was 100% sure the Hartz flea treatment was the cause of Abby’s illness. As a result of using this deadly $5.00 treatment Abby had to stay in the hospital overnite where she was throroughly bathed, given IV treatments, injections of muscle relaxer, charcoal to help clean her system, etc at the cost of $800+. The vet said she treats at least 2 pets per week because loving owners who knew no better used Hartz products on their pets. She also said the majority of the smaller pets didn’t survive the damage done by this product. How in the world can this company continue to be in business! Have the “powers that be” at Hartz no conscience or compassion for animals at all! There is nothing on the product package that alerts potential customers of the possible side effects of use of these products. Is this company held to a lower standard just because they are manufacturing products for pets? Shouldn’t they be required to make buyers aware of potential harms and even fatalities suffered as a result of use or their products? The folks at Hartz can rest assured I will tell everyone everywhere I go about my experience and I will definitely enourage everyone I encounter not to use Hartz products. I would love to see someone persue a law suit against this money hungy company. Quite obviously their concern lies with profit, not the well being of the user!
