movement behind eyeline training inspiration please!

[SEL]

Baby cob has had a couple of bad experiences recently which have really unsettled him. Two involved dogs running up behind him (one was behind a garden fence) and the other was a jogger who waited until we went past then took off running - I nearly hit the deck with that one as he leapt forward with a huge buck He's also hating cyclists coming up behind him

He does long rein and I might try that around our fields but my roads aren't safe enough to long rein on.

Any ideas (I'm on my own) as to how I can get him used to those sudden movements behind him and not completely over react? I've started leading around the roads in hand again, but if anyone has useful exercises I can try I'd really appreciate it

Do you have a tame ninja cyclist who can accompany you out on your hacks to help deal with and manage the unexpected?

Borrow a well trained teen to accompany you, chase them on a cycle so pony gets the idea, then get them to ride beside you, then work backwards.
They can then progress to gym activities, star jumps etc on foot.

I borrowed a lanky 12 Yr old who got right into it when I 1st got B going.
A few quid made his day!
