I am looking at purchasing an Appaloosa. I will be meeting him on Saturday. I know nothing about the breed. A few people have said they heard they can be difficult. Looking for opinions. I have ridden a few over the years and they seemed lovely. At 58 I am looking for what probably will be my last horse and want one that is safe. I have enjoyed two wonderful horses over the years but have also had a few mishaps on ones that I did not know which has given me a bit of anxiety. Thanks in advance for input.
