We bought a great dane from this breeder who has developed several illnesess like elbow joint disease by the time he was 1 year old. He also suffered from tendon problems and sensitive stomach. By the time he was 2 he had severe arthritis. We followed the feeding guidlines of the breeder from the day we picked him up. He has been seen by a orthopedist specialist every 30 days to have bloodwork done to balance the pain medication and acid controller. The dogs she ownes are beautiful but seem to produce puppys with genetic problems. Also the male she ownes "Xanadu" shows aggressive behavior. He would not let anyone even close to him. All the dogs were kept in a stall in a horse barn (Tampa fl)and didn't seem very friendly.
