Yesterday I used Hartz Ultra Guard on my Star Sparkle. Today she is showing signs of poisoning. Since we live in the country away from any vets, I have tried using hydrogen Peroxide to induce vomiting. I am hoping that she makes it through the night. I cannot believe that this company has this product for sale with all the post that I have been reading. I know that the current administration will not do anything to stop this but, I hope that the new administration will make this company pay for the damages that this has caused to families.
