How sad! When my family got our Great Dane mix, many many years ago, we got her third-hand, from people who didn't know the first thing about the nutritional needs of a Great Dane pup. Not only was she tiny, she had scars on her face from their elderly poodle, she had rickets from the malnutrition - and, get this - they had been teaching her to jump up into their arms when they clapped their hands!!!! Like I said, not a clue. I am glad that Zeus, like Gracie, has made his way to a real home. Gracie, by the way, ended up about 145 pounds, and lived to be 14 1/2 - unheard of for a Great Dane - and was a very happy, goofy puppy all her life!
