Tiffany’s Heart Condition. Hi Dr. Carol, We started using your VitaLife vitamins for our dog Tiffany in particular she had a heart murmur and was slowing down quite a bit. About a month after we started the vitamins. She seemed to have more energy, and was her saucy self until the day she died. We have continued giving them to our other dogs to keep them as healthy as possible. Oooops! I forgot to send a picture of our dog Brandy. She is on your vitamins too.
