collecting

Question
I have a three year old quarter horse gelding. He has been rode for about 1 year. He is currently ridden in a full check snaffle bit. When he trots he sticks his nose out and raises his head. How do i teach him to collect?

Answer
Dear Hillari,
I am currently out of the country and will not be able to respond to questions until later this month as my internet access is VERY limited.
I would suggest that you could either consult with one of our other experts, or please get back to me at the beginning of August.
Sincerely,
S. Evans
