Hartz products are not safe!

As someone who works in small animal medicine I will tell you what any vet or tech will tell you: hartz products are not trustworthy and I would highly reccommend using a different brand. Especially with medicated products such as this one. There are other generics/inexpensive options out there that are much safer than these. Although they’re cheap they could cost you hundreds of dollars in an expensive emergency vet visit. There is literally a website dedicated to hartz victims, due to flea and tick products that resulted in a lot of pet fatalities years ago.
