Oh, Deer!

[QUOTE=Southernboy;7046396]
This might not work for you. I had an OTTB that was scared of the attack deer which we encountered several times each ride. When we would be attacked, I started giving a little heel and a very enthusiastic “let’s go get’em” and chased them. When my horse realized that the deer would run from us, it quit being an issue with him.[/QUOTE]

I did this with my standardbred! Also did it with geese. It was beneficial for helping with his canter, too. Worked great.
