Most herding-type dogs can't resist a moving target unless they are very well trained. If that was the only route I could go and I had to go that way, I would get off my bike and start walking it prior to entering the "dog's territory" which is probably the start of the yard, not the gate or area it runs out of. It might bark and come out to greet you but walking shouldn't incite its herding/prey instincts.

Meanwhile, I would definitly be pursuing having the dog owners contacted by the police or sheriff or animal control so you wouldnt have to be walking your bike. Who is the elected official in your county or precinct? A letter with carbon copy to dog's owner might get some attention.

If your are a really patient, tranquil type you might be able to acclimate the dogs to your movement past them but this could take weeks and is really not your job.

I have had success with yelling "No. Bad dog" but then again I'm training a rottweiller/shephard cross pup and am at the top of my authoritarian dog-voice at the moment.

Good luck and get those letters flying! My the dimwits with the dogs don't know your officials are lame in this area and will do something on their own.
