As your drawing of the trot demonstrated, it's very difficult to get the
horse to go up and down (without looking like it's a mistake in the
animation) I have altered it a bit now by changing the neck angle.

"                       \r\n"+
"            ,~         \r\n"+
"          ~/(\         \r\n"+
"   ~ ____~/ |`         \r\n"+
" ~~~( )___(_|_         \r\n"+
"    |/\_ _/   \        \r\n"+
"   /             ejm98 \r\n",

I think that having an upright neck gives more of an illusion of the up
and down motion. I also slowed it down fractionally to give it a
choppier look (again, when I slowed it down to the right speed for a
trot, it was too choppy and looked like an error in the animation).
