I was given a letter with some information on the care of my doberman. Anyways this is my FIRST dog EVER so this is all new to me. She is a beautiful $2,000 darling. I was given instructions on feeding her & about vitamin supplements. One of the things was a long informative page on Vitamin C. I was told it was ESSENTIAL to give her 1000 mg's of Vitamin C every day then at 5 months increase it to 1500 mgs of C. Anyways a lot of the "information" seemed like something akin to a snake oil salesman. Anyways just in case I have faithfully been giving her the Vitamin C supplement in additon to 400 IU of E & 8000 IU of A & 400 IU Vitamin D. Anyways can some of you more knowledgable help me out in this? I'm currently feeding her Royal Canin & I'm about to switch over to Innova for pups. She'll be 5 months on July 22. I was told the Vitamin C would help her ears after getting them posted. Well since I last posted her ears (which was only once since I bought her) she's NEVER had any problems with them.
