Horse rocks trailer on way home
My gelding has begun to develop a really annoying habit. He travels well, doesnt sweat, loads well. He perhaps is still a little nervous but he's getting much better. On the way to wherever we are going he travels fantastically: walks up, stands quietly in float while I do bum bar, stands happy in the float waiting for me to go. Doesn't move excessively, unloads happy as.
On the way home, loads great, stands great, then as we get going he starts doing something that causes the trailer to start swinging. Theres a little window at the front and I can see it's not his whole body moving because his head is mostly stationary. He does occasionally fling his head around on the way home but it's not what is causing the swaying. Its rhythmatic: if I was to guess I'd say hes rocking from one foot to the other. Does it from about the first ten minutes to the whole way home- our trips are usually about thirty minutes but do vary in direction. He seems to know exactly when he is about fifteen minutes from home and starts getting impatient.
On longer trips he doesnt do this.
I have tried: giving him hay, keeping his head tied, keeping his head untied, travelling him with a buddy, wrapping his legs, unwrapping his legs. Nothing makes a difference! Hasnt injured himself really, has taken a bit of hair off his face from head flinging but nothing on his legs etc.
Any suggestions? It's a bit disconcerting to look behind ya and see the trailer going from side to side. Not dangerous (stays within the lines) but also doesnt feel safe and I'd like to stop it.
