But, about a month or two ago, she changed suddenly. First, she started to randomly fear water. She refused to cross the creek, which she had crossed many, many times before. Then she refused to so much as step in a puddle.
Next, she started not listening to the little kids who usually rode her in lessons. You had to MAKE her do what you wanted. She would fight you every inch of the way.
Then she started to act like a hunted rabbit. She spooks at everything, and at nothing. She won't stand tied. She won't even let her owner give her shots, which she didn't have ANY problems with before! She ran her owner over!
It's so suddenly and random... What do you think is the problem? I can answer all the questions I can, but she isn't my horse. I may know enough to help though.
