I got my two daughter’s a puppy for Christmas. He has been a great dog. He even perked up another dog we have because he lost his playmate. Well I resently purchased some Flea and Tick Shampoo by HARTZ. The puppy (Gizmo) is now well over 6months of age. We gave hi a bath last night with this Shampoo and now he is having convolutions. We are not. financily stable to take him to a vet. So we are doing the best we can with what we have. I will no longer use there products and advising everyone I know not to use there products. Gizmo is doing better than what he was about 12 today. So I pray he just continues to improve. Heartz should not be able to produce and sell products that are harmful to our loved ones. They may walk on all fours but they are still family.
