So I basically didn't read anyone replies since my last post, sorry! I hope you all know I appreciate them anyway!
Anyway; I finally got her to go down the slope and into the water by first doing a lot more groundwork, lounging for respect and trust and a bunch of other stuff like that. I've known had her for 3 weeks and a couple days incase anyone was wondering.
I went out by myself to the creek yesterday, I first did that "going to water is good, going away is bad" under saddle with both slopes down. After a while when she would stand facing the slope, calmly, though still didn't go down.
I hoped off, we were riding in a rope halter btw, and stepped down into the pebble part of the creek. I did the same thing as above, giving her praise if she looked down off the bank. After a while she stepped down from the bank, no going down the slope.
After that she now goes in like normal and comes out. Today we went sort of swimming in the creek with my friend. We still need to gain confidence in each other, but I plan to do a lot more trail riding to help her. Also yesterday we went in about every creek I could find, she jumped over them at first but after letting her do it again she was fine.
Once again guys, thanks for replying and giving your opinions on the matter. Sorry this whole thing sort of got twisted and crazy. Live, laugh, ride! ^_^
