My year 1/2 old Papillon became very sick after using the sergeants gold flea and tick drops, he had scratching, uncontrollable full body twitching and heavy breathing. We brought him to an emergency vet at 11pm, they gave him benadryl which did not help!! He had a reverse reaction to the benadryl he did not sleep for 24 hrs. now he is finally starting to sleep !!! I feel responsible for putting my baby in such danger for not getting all the facts, but i know it is all them for selling such a dangerous and toxic product. This product should never be sold. I feel lucky to have him and I’m feel sad for all the the ones that died from this product.
